Patent Images
1. A FLOW CONTROL VALVE FOR CONTROLLING FLOW OF FLUID THERETHROUGH COMPRISING:
- A VALVE HOUSING, SAID HOUSING HAVING A TOP, A BASE END ENCLOSING A COMPARTMENT, SAID HOUSING HAVING ALIGNED INLET AND OUTLET PORTS IN COMMUNICATION WITH SAID COMPARTMENT;
A SEATING SURFACE SURROUNDING SAID INLET PORT;
A GATE DISPOSED WITHIN SAID COMPARTMENT FOR MOVEMENT IN A PATH NORMAL TO SAID PORTS, SAID GATE HAVING A CYLINDRICAL CHAMBER OPENING THROUGH ONE SIDE THEREOF, THE AXIS OF SAID CYLINDRICAL CHAMBER BEING PARALLEL TO THE AXIS OF SAID ALIGNED PORTS;
A PASSAGEWAY PASSING THROUGH SAID GATE PROVIDING FLUID COMMUNICATION BETWEEN SAID COMPARTMENT AND SAID CHAMBER;
MEANS FOR SEALING SAID PASSAGEWAY;
A LATERALLY MOVABLE PISTON DISPOSED IN SAID CYLINDRICAL CHAMBER HAVING AN INNER AND OUTER FACE;
AN ANNULAR SEALING PROJECTION FORMED INTEGRALLY ON THE OUTER FACE OF SAID PISTION;
MEANS COMMUNICATING WITHS AID INLET PORT AND SAID CYLINDRICAL CHAMBER FOR PASSING SAID FLUID TO AID INNER FACE OF SAID PISTON PROVIDING FOR THE ESTABLISHMENT OF A PRESSURE DIFFERENTIAL ACROSS SAID PISTON, SAID PRESSURE DIFFERENTIAL ACTING TO SEALABLY SEAT SAID PISTON AGAINST SAID SEATING SURFACE;
RESILIENT MEANS ACTING IN OPPOSITION TO SAID PRESSURE DIFFERENTIAL TO RETAIN SAID PISTON IN SAID CYLINDRICAL CHAMBER;
A FLEXIBLE SEAL MEANS DISPOSED BETWEEN SAID PISTON AND SAID CHAMBER PROVIDING FOR A FLUID TIGHT SEAL THEREBETWEEN;
MEANS CONNECTED TO SAID GATE FOR ALIGNING SAID PISTON MEANS CARRIED BY SAID GATE FOR ALLOWING GENERALLY FRICTION-FREE MOTION OF SAID VALVE GATE RELATIVE TO SAID HOUSING.
