         [0116]    When the piston and rod  42  move sufficiently to the left, the sleeve engaging portion  44   c  contacts the intrusions  48   c  and further movement of the piston and rod  42  to the left pushes the sleeve valve  48  to the left, dis-aligning the inlet port  45   a  from the inlet window  47   a  and aligning the outlet port  45   b  with the outlet window  47   b  halting the flow of heated water  36   b  into the piston assembly  40  and initiating the second flow of heated water  36   c  from the piston assembly  40 . The spring  46  then pushes the piston and rod  44  back to the right while the second flow of heated water  36   c  continues to be released from the piston assembly  40 . At the end of the rightward motion of the piston and rod  42 , the piston portion  44   b  engages the intrusions  48   c  to push the sleeve valve  48  back to the right to realign the inlet port  45   a  from the inlet window  45   a  and dis-aligning the outlet port  45   b  with the outlet window  47   b  to reinitiate the flow of heated water  36   b  into the piston assembly, and the cycle repeats. 
         [0117]    A cross-sectional view of a second simpler but potentially less effective piston assembly  40   a  with the piston  50   a  and rod  44  to the rig ht is shown in  FIG. 11A . The second flow of heated water  36   b  is entering the cylinder  42   a  through inlet ports  45   a  in the right end of the cylinder  42   a  driving the piston  50   a  and rod  44  to the left compressing the spring  46 . A flap valve  41  allows the flow  36   b  into the cylinder  42   a  and a sliding valve  48   a  blocks the flow  36   c  from the cylinder  42 . 
         [0118]    A cross-sectional view of the second piston assembly  40   a  partially filed and with the piston and rod moving partially to the left is shown in  FIG. 11B . The cylinder is filling with the second flow of heated water  36   b  through inlet port  45   a  continuing to drive the piston  50   a  and rod  44  to the left. The flap valve  41  continues to allow the flow  36   b  into the cylinder  42   a  and the sliding valve  48   a  continues to block the flow  36   c  from the cylinder  42   a.    
         [0119]    A cross-sectional view of the second piston assembly  40   a  with the piston  50   a  and rod  44  farther to the left is shown in  FIG. 11C . The second flow of heated water  36   b  continues to enter the cylinder  42   a  through the inlet port  45   a , and outlet port  45   b  is now uncovered and the third flow of heated water  36   c  is releasing through the outlet port  45   b . The flap valve  41  blocks the inlet port  45   a  and the piston  50   a  has moved the sliding valve  48   a  to allow the flow  36   c  from the cylinder  42   a.    
         [0120]    A cross-sectional view of the second piston assembly  40   a  with the piston  50   a  and rod  44  urged to the right by the spring  46  is shown in  FIG. 11D . The flap valve  41  continues to block the inlet port  45   a  and the sliding valve  48   a  continues to allow the flow  36   c  from the cylinder  42   a.    
         [0121]    A cross-sectional view of the second piston assembly  40   a  with the piston  50   a  and rod  44  traveling back to the right is shown in  FIG. 11E . The flap valve  41  continues to block the inlet port  45   a  and the piston  50   a  is moving the sliding valve  48   a  blocking the flow  36   c  from the cylinder  42   a.    
         [0122]    A side view of a first water dispersion assembly  30   a  is shown in  FIG. 12A  and top view of a rotating first distribution disk  70   a  of the first water dispersion assembly  30   a  is shown in  FIG. 12B . The water dispersion assembly  30   a  includes the piston assembly  40 , a distribution disk assembly  72 , a spindle  62   a , and a spiral guide  64   a  (see  FIG. 13 ), a spring  66  pressing down on the spiral guide  64   a . The third flow of heated water  36   c  is carried from the piston assembly  40  a non-rotating portion  62   a  (see  FIG. 15 ) of the spindle  62 . The distribution disk assembly  72  rotates with a rotating portion  62 ″ of the spindle  62   a  and a nozzle  74  slides radially in a slot  70 ′ in the distribution disk  70   a . A spring  68  pulls the nozzle  74  towards the center of the distribution disk  70   a . The nozzle  74  further engages the spiral guide  64   a  to slide the nozzle  62  radially outward along slot  70 ′ as the distribution disk  70   a  rotates. The rod  44  of the piston assembly  40  provides rotation of the distribution disk  70   a  by pushing against teeth  70 ″ on the perimeter of the distribution disk  70   a . A fourth flow of heated water  36   d  runs from the spindle  62   a  to the nozzle  74 . 
         [0123]    A bottom view of the spiral guide  64   a  is shown in  FIG. 13  and a cross-sectional view of an edge portion  64 ′ of the spiral guide  64   a  is shown in  FIG. 13A . The spiral  65  is an indentation (or groove) in the bottom of the spiral guide  64   a  and the groove  65  grows shallow at the edge portion  64 ′ of the spiral guide  64   a . When the nozzle  74  reached the edge portion  64 ′, the spiral guide rises, and the nozzle  74  is released and skips across the grooves  65  the nozzle  74  to an initial location proximal to the center of the distribution disk  70   a  and starts moving out again, thus providing a concentrated distributed flow of heated water into the brewing material  28 . While a spiral guide  64   a  is shown biased towards the distribution disk  70   a , in other embodiments the spiral guide may be fixed, and the nozzle  74  may be biased towards the spiral guide  64   a.    
         [0124]    A side view of the nozzle  74  is shown in  FIG. 14A , a top view of the nozzle  74  is shown in  FIG. 14B , and a bottom view of the nozzle  74  is shown in  FIG. 14C . The nozzle  74  includes a spiral engaging tip  74   a  which may be pointed, offset, rounded, or any shape suitable to cooperate with a groove  65  and to skip across the spiral guide  64   a  after disengaging from the groove  65 . A stop portion  74   b  resides above a guide portion  74   c  which slides in the slot  70 ′. The heated flow of water  36  is released through a port  74   d  in the bottom of the nozzle  74 . 
         [0125]    The spindle  62   a  including a fixed portion  62 ′ and a rotating portion  62 ″ is shown in  FIG. 15 . The rotating portion  62 ″ rotates with the distribution disk  70   a . The fourth flow of heated water  36   d  enters the spindle  62   a  through stationary port  63   a  and is released from the spindle  62 ″ through rotating port  63   b.    
         [0126]    Six sequential positions of the nozzle  74  of the first water dispersion assembly  30   a  are shown in  FIGS. 16A-16F . As the distribution disk  70   a  rotates, the nozzle  74  moves out radially through cooperation with a second spiral guide  64   a . When the nozzle  74  reaches the end of the slot  70 ′, the nozzle  74  disengages from the spiral guide  64   a  and returns to its initial location proximal to the spindle  62   a.    
         [0127]    A side view of a second water dispersion assembly  30   b  is shown in  FIG. 17A , a second side view of the second water dispersion assembly  30   b  is shown in  FIG. 17B , and a top view of a second distribution disk  70   b  of the second water dispersion assembly  30   b  is shown in  FIG. 18 . The water dispersion assembly  30   b  includes an arm  86  extending from a pivot block  84 . A spring  68  pulls the arm  86  outward, and a rotating second spiral guide  64   b  guides the arm  86  inward. The spiral guide  64   b  is very similar to the spiral guide  64   a , except the inner most spiral of the spiral guide  64   b  reduces in depth to disengage the nozzle  74  from the spiral guide  64   b  to allow the spring  68  to pull the arm  86  outward, the nozzle  74  skipping over grooves  65 , to return to an outside position to repeat the inward travel of the nozzle  74 . 
         [0128]    A cross-sectional view of the distribution disk  70   b  taken along line  19 - 19  of  FIG. 18 , is shown in  FIG. 19 . The distribution disk  70   b  includes concentric troughs  80  having passages  82  to release heated water from the distribution disk  70   b  into the brewing material  28 . Each trough  80  is consecutively filled with heated water as the arm  86  pivots inward. The heated water is distributed angularly by rotation of the distribution disk  70   b  caused by the piston assembly  40 . 
         [0129]    Six sequential positions of the nozzle of the water dispersion assembly  30   b  are shown in  FIGS. 20A-20F . As the arm  86  is caused to pivot by the spiral guide  64   b , the nozzle  74  sequentially fills the troughs, from the outermost trough, to the inner most trough, and then repeats. 
         [0130]    An embodiment of the first dispersion assembly  30   a ′ with rotation provided by a motor  88  is shown in  FIG. 21 , and an embodiment of the second dispersion assembly  30   b ′ with rotation provided by the motor  88  is shown in  FIG. 22 . The motor  88  replaces the piston assembly  40 , and the flow of heated water may be from a drip coffee maker, or from a coffee maker having a pump to circulate the flow of heated water. 
         [0131]    Motion of a third water dispersion assembly  30   c  is shown in  FIGS. 23A-23C  as a carrier  90  is shown traveling along a rail  92  of a third spiral guide  64   c . A side view of the carrier  90  is shown in  FIG. 24 , a top view of the carrier  90  taken along line  25 - 25  of  FIG. 24  is shown in  FIG. 25 , and a bottom view of the carrier  90  is shown in  FIG. 26 . The carrier  90  includes an idler roller  91   a  and driven roller  91   b  sandwiching an inverted “T” rail  92 . The driver roller  91   b  is driven by a motor assembly  94  rotationally attached to the nozzle  74 . The motor assembly  94  receives the third flow of heated water  36   c  and may be a water driven motor (see  FIGS. 27 and 28 ) or be an electric motor  100  receiving electrical power through conductors  99  (see  FIG. 29 ). The motor assembly  94  may be rotationally constrained by a water line carrying the third flow of heated water  36   c  to the motor assembly  94 , or by a telescoping arm  94   a , or be otherwise rotationally constrained to allow only some rotation of the motor assembly  94  as the carrier  90  travels along the spiral guide  30   c.    
         [0132]    A cross-sectional view of a water driven carrier  90  taken along line  27 - 27  of  FIG. 26  is shown in  FIG. 27 , and a cross-sectional view of the water driven carrier  90  taken along line  28 - 28  of  FIG. 27  is shown in  FIG. 28 . The water driven carrier  90  includes bearing  95   a  allowing a motor case  94 ′ to pivot on the nozzle  74  and bearing  95   a  allowing the nozzle  74  to rotate in a guide plate  93  and to rotate the driven roller  91   b . The idler roller  91   a  freely rotates on a vertical shaft fixed to the guide plate  93 . The third flow of heated water  36   c  tangentially enters the motor case  94 ′ through port  98  and cooperates with fins  96  attached to the nozzle  74  to rotate the nozzle  74  and thus also rotate the driven roller  91   b  causing the carrier  90  to travel along the rail  92 . Ports  97  in the nozzle  74  receive the third flow of heated water  36   c  and the nozzle  74  releases the flow of heated water  37  (see  FIG. 3 ) into the brewing material  28 . 
         [0133]    A cross-sectional view of a water driven carrier  90   a  having an offset nozzle  74   a , taken along line  27 - 27  of  FIG. 26 , is shown in  FIG. 27A . The offset nozzle  74   a  resides generally opposite to the port  98  and may provide a stronger flow of water out of the motor case  94 ′. 
         [0134]    A cross-sectional view of an electric powered carrier  90  taken along line  27 - 27  of  FIG. 26  is shown in  FIG. 29 . Electrical conductors  99  run parallel to the third flow of heated water  36   c , and into the motor case  94 ′ to an electric motor  100 . The electric motor  100  is constrained from free rotation within the case  94 ′ and rotates the nozzle  74  with respect to the case  94 ′. The electric powered carrier  90  is otherwise similar to the water powered carrier  90 . 
         [0135]    A toothed drive gear  91   b ′ and toothed rail  92 ′, of the third water dispersion assembly  30   c , having engaging teeth are shown in  FIG. 30 . The teeth provide improved engagement of the drive gear  91   b ′ and rail  92 ′. 
         [0136]    A fourth water dispersion assembly  30   d  including an X-Y positioned nozzle is shown in  FIG. 31 . A first motor  100   a  positions a horizontal rail  104  on lateral rails  102 , and a second motor  100   b  positions the nozzle  74  laterally on the horizontal rail  104 . The motors  100   a  and  100   b  are microprocessor controlled to position the nozzle  74  to disburse the flow of heated water into brewing material. 
         [0137]    A fifth water dispersion assembly  30   e  including an R theta positioned nozzle  74  is shown in  FIG. 32 . A telescoping arm  112  is motor driven to position the nozzle  74  radially and a pivot  110  is motor driven to position the nozzle  74  angularly. The telescoping arm  112  and pivot  110  are microprocessor controlled to position the nozzle  74  to disburse the flow of heated water into brewing material. 
         [0138]    A coffee maker  10   a  according to the present invention and including a first water dispersing assembly  200   a  is shown in  FIG. 33A . The water dispersing assembly  200   a  is attached over the brewing chamber  11  after the brewing material  28  is deposited into the brewing chamber  11 .

         [0139]    A second coffee maker  10   b  according to the present invention and including a water dispersing assembly  200   b  attached to the coffee maker lid  14  is shown in  FIG. 33B . Arms  202  are attached to the water dispersing assembly  200   b  to disperse water into the brewing material  28  during brewing. The water dispersing assembly  200   b  may include a baffle  201  residing under the arms  202  to separate the arms  202  from the brewing material  28 .

The bearing connector  214  includes external tabs  214 ′ which engage internal slots  204 ′ in the attachment bridge  204 , and the water dispersing arms  202   a  include internal tabs  202 ′ which engage external slots  210 ′ in the locking shaft  210 , to assemble the water dispersing assembly  200   a . The tabs and slots allow the water dispersing assembly  200   a  to be easily disassembled for cleaning. 
         [0142]    A more detailed exploded view of the water dispersing assembly  200   a  is shown in  FIG. 36 , engaging clips  204   a  of the attachment bridge  204  and bearing connector  214  are shown in  FIG. 37 , and engaging features of the water dispensing arms  202   a  and the locking shaft are shown in  FIG. 38 . 
         [0143]    A side view of the water dispersing assembly  200   a  is shown in  FIG. 39A , an end view of the water dispersing assembly  200   a  is shown in  FIG. 39B , a top view of the water dispersing assembly  200   a  is shown in  FIG. 39C , and a bottom view of the water dispersing assembly  200   a  is shown in  FIG. 39D . A cross-sectional side view of the water dispersing assembly  200   a  taken along line  37 A- 37 A of  FIG. 39C  is shown in  FIG. 40A , and a cross-sectional view of the water dispersing assembly  200   a  taken along line  37 B- 37 B of  FIG. 39A  is shown in  FIG. 40B . The flow  36   b  from the heating element  34  is provided to the water dispersing assembly  200   a  and a spray pattern  218  from the water dispensing arms  202   a  result. 
         [0144]    A top isometric view of the water dispersing arms  202   a  is shown in  FIG. 41A , a bottom isometric view of the water dispersing arms  202   a  is shown in  FIG. 41B , a side view of the water dispersing arms  202   a  is shown in  FIG. 42A , an end view of the water dispersing arms  202   a  is shown in  FIG. 42B , a top view of the water dispersing arms  202   a  is shown in  FIG. 42C , and a bottom view of the water dispersing arms  202   a  is shown in  FIG. 42D . Right and left arms  203  of the water dispersing arms  202   a  are laterally (e.g., in the horizontal plane) offset by a center portion  203   a  a distance L. 
         [0145]    A side view of the water dispersing arms  202   a  and a spray pattern  218  is shown in  FIG. 43A  and an end view of the water dispersing arms and the spray pattern  218  is shown in  FIG. 43B . The water dispersing arms  202   a  include ports  216  providing the spray pattern  218 . The ports are angled an angle A from a vertical centerline CL of the water dispersing arms  202   a . The angle A is preferably between 30 and 60 degrees, and is more preferably about 45 degrees. The angle A is selected to provide torque to rotate the water dispersing arms  202   a  during operation. The offset L is selected to direct the spray pattern  218  from both arms  203  to contact the brewing material along a generally straight line (see  FIG. 43B ). In the absence of the offset L, the contact of the two spray patterns from the two arm  203  would be displaced outwardly. 
         [0146]    A top view of water coverage provided by the water dispersing arms  202   a  is shown in  FIG. 44A  and a distribution of water coverage provided by the water dispersing arms  202   a  is shown in  FIG. 44B . The spray pattern  218  provides the same amount of water to each ring, however, the outside ring has about eight times the area of the inside ring, and thus receives about one eighth the water per unit area. 
         [0147]    A top view of water coverage provided by second water dispersing arms  202   b  is shown in  FIG. 45A  and a distribution of water coverage provided by the second water dispersing arms  202   b  is shown in  FIG. 45B .

The water dispersing arms  202   c  include center ports  216   a  aimed directly down. The ports  216   a  do not require angling because the ports  216   a  aim the spray pattern directly down. 
         [0150]    An example of components of a non-drip coffee maker  10   c  are shown in  FIG. 49 . The components include the water tank  18 , a second heater  34   a . Unlike the drip coffee maker, the coffee maker  10   b  may include a mechanical pump  302  controlled by a processor  300 . The processor  300  may control the pump  302  to provide pulses of water  36   b  for a water dispersion system including the piston assembly  40 , or may provide either a pulsed or continuos stream of water to a water dispersing assembly  200   a . The processor  300  may further control a solenoid  304  or similar device replacing the piston assembly  40  in embodiments including the piston assembly  40 .
