Abstract

1435191 Fluid-pressure servomotor systems REFRIGERATING SPECIALTIES CO 1 May 1973 [1 May 1972] 20633/73 Heading G3P A pressure regulator for the outlet of a refrigerator evaporator and which can be adapted for different functions comprises an adaptor member 15 sandwiched between a bonnet 12 and a body member 14. The bonnet carries an adjustable spring 80 acting on a diaphragm 28 clamped between the bonnet and the adaptor member to force the diaphragm against a valve seat 34 which inter-connects the recesses 20, 40 of the adaptor member. The body member 14 has piston valve means formed by an actuating piston 42 and a closure member having V-slots 114 and a conical sealing surface 111 which closure member cooperates with a seat 106 to control flow between an inlet 100 and an outlet 102. The inlet is connected by passages 126, 58 to a manifold space 48 in the adaptor member which space is connected to a screwed port 46 and two passages 60, 62 which open externally at surface pads 50, 52. A further pair of passages 64, 66, which communicate respectively with the recesses 40, 20, open externally at the pads 50, 52. A block (68) Figs. 6 and 7 (not shown) can be bolted to each pad to interconnect the respective passages 62, 66 and 60, 64 or to seal them from each other. If passages 62, 66 are inter-connected by a block (68) the diaphragm 28 will respond to excess pressure in inlet 100 to move away from the valve seat 34 to allow inlet pressure to act on the piston 42 to open the closure member against the spring-loading 120. An adjustable plunger can be arranged to prevent full closure of the closure member. A block (68) may be replaced by a pressure-responsive diaphragm pilot valve in parallel with or a solenoid-operated pilot valve in series with the diaphragm valve. Alternatively the bias spring 80 may be supplemented by a fluid-pressure admitted to the bonnet and responsive to a thermostat or a humidstat. The bias spring 80 may also be adjusted by a solenoid (142), or a motor driven cam (160) responsive to temperature. The connection between passages 126, 58 can be closed by relative rotation of the body and adaptor members or by rotation of the gasket 59 therebetween.
