Title: Thermally-tuned rotary labyrinth seal with active seal clearance control
Inventor: STARLING TRACY
IPC: F01D11/18
Filed: 1991-01-17
Abstract: ABSTRACT OF THE DISCLOSURE       A thermally-tuned rotary labyrinth seal  for a gas turbine  engine  includes  an  inner annular seal member having axially spaced, radially projecting annular seal teeth, and an outer annular seal member having a stepped honeycomb structure which face the annular seal teeth of the inner seal member and define therewith axially spaced regions  bounded  by the  seal  teeth  and  honeycomb structure.    The  seal  teeth  and  stepped honeycomb structure cooperate to inhibit gas flow  from one region to the next.   Also, the seal has inlet  and  outlet vent holes  defined   through  the   honeycomb  structure  at respective upstream and downstream ends  thereof which communicate with correspondingly  located  ones  of  the regions.  The inlet and outlet vent holes  are  aligned along respective planes extending radially relative to a longitudinal  axis  of  the engine  and  the  holes are disposed at angles  extending  in tangential  directions along the radial planes.   Further, the seal includes an annular  housing  attached  on  an  outer  side  of  the honeycomb  structure   which  defines  a  single  axially elongated  annular  cavity   spanning   the  honeycomb structure.     The  cavity  interconnects  in  flow communication  the inlet and outlet  vent  holes   for providing gas flow in heat transfer relationship along the outer side of the honeycomb structure from the inlet vent holes  to the outlet vent  holes  to  provide active seal clearance control.

Title: Thermostatically controlled mixing valve
Inventor: MACDONALD ROBERT
IPC: G05D23/13
Filed: 1992-03-13
Abstract: A  thermostatically  controlled  mixing  valve  having  a modular  cartridge  mounted  in  a  housing.   The  cartridge comprises a tubular sleeve having rotatably disposed therein a hollow cylindrical housing.   The bottom of the cylindrical housing has a volume control valve plate attached against rotational movement thereto.  The volume control valve plate cooperates with a  fixed valve plate with which  it is  in surface-to-surface contact to control the volume  of water flowing into the cartridge.  The fixed valve plate is affixed against rotational movement to a nose piece which is fixedly attached  to  the bottom of  the  tubular sleeve.   An  inner housing is disposed within the hollow cylindrical housing and defines therewith cold and hot water inlet passageways which are in communication with a mixing chamber in the interior of the inner housing through hot and cold water supply openings.          A  thermostat  construction  responsive  to  the  mixed  water temperature is axially movably disposed in the mixing chamber and is operably connected to valving means adapted to open and close the hot water supply opening and cold water supply opening.   The  valving  means  comprise  a  cylinder  fixedly mounted on the top of the inner housing with the bottom of the cylinder and the top of the inner housing defining the hot water  supply  opening,  and  with  the  top  of  the  cylinder defining with an inner shoulder in the cylindrical housing the cold water supply opening, and a piston operably connected to said thermostat construction and axially slidably disposed in said cylinder.  Upward movement of the piston in the cylinder serves  to  close  off  the cold water  supply opening while downward   movement of the piston serves to close off the hot water  supply  opening. An  increase  in  the  mixed  water temperature in the mixing chamber results in axially downward movement of the thermostatic element with consequent downward movement of the piston thereby resulting in restriction or closure of the hot water supply opening. A decrease in the mixed water temperature  in the mixing chamber results  in axially upward movement  of  the  thermostatic  element  with consequent upward movement of the piston thereby resulting in restriction  or  closure of  the  cold  water  supply  opening thereby maintaining a preselected water temperature in the mixing chamber.
