Title: Self flushing irrigating valve
IPC: B05B15/02
Filed: 1973-03-23
Abstract: A self-flushing irrigating valve formed, at least in part, of an elastically deformable material which, when subjected to differential pressures below a preselected value, occupies an open position forming a passage for the flushing of water therethrough; and when subjected to differential pressures above a preselected value, forms a constricted passage for trickle flow of water therethrough. The valve, when in its trickle flow condition, tends to effect further constriction on further increase in differential pressure thereby tending to produce a uniform flow rate through a range of effective pressures.

Title: Pressure operated power wrench
Inventor: POORU HAINTSU WAGUNAA
IPC: B25B21/00
Filed: 1994-02-02
Abstract: PURPOSE: To reduce the length of a resetting means and the size of a whole housing by providing at least inside and outside subsidiary pistons and serving the outside subsidiary piston as a cylinder for the inside subsidiary piston. CONSTITUTION: Pressure introduced into an operating cylinder 17 moves an operating piston 25 forward and a joining member 27 is moved while being engaged with an arm 41 for rotating a holding ring 42 together with an annular member 43. During operating stroke, pressure medium is pushed out of subsidiary cylinders 21, 21a through holes 39, 38. It is in reverse operation after the operating stroke is finished for applying pressure to a connector 34 to cause a connector 33 to be connected to a tank. The pressure is thus introduced into the subsidiary cylinder 21 to drive the outside subsidiary piston 29 followed by the inside subsidiary piston 30 to the right side.  As the total capacity of the subsidiary cylinder 21, 21a is smaller than the capacity of the operating cylinder 17, a whole slider 60 can be driven to an original reset position with a relatively small amount of operating liquid.
