Abstract

1331360 Reciprocating pumps and motors STATHAM INSTRUMENTS Inc 17 Sept 1971 [25 Sept 1970 12 Aug 1971] 43542/71 Headings F1A and F1M [Also in Division F4] A thermodynamic refrigerating engine with a cycle operating between two levels of subatmospheric temperature, includes an evaporation zone 1 exposed to the temperature to be controlled by the engine, a condensation zone 3 kept at a low temperature by dry ice, tubes 11 disposed within the condensation zone, a feed pump 4 disposed within a conduit connecting to condensation zone to the evaporation zone, and a motor 5 connected to drive the pump 4 and connected in a vapour conduit between the evaporation zone and the condensation zone so as to be driven by vapour from the evaporation zone and to feed its exhaust to the condensation zone. A fan is positioned adjacent to the zone 1 and is driven by a second motor 6, the motor 6 also being connected in a vapour conduit between zones 1 and 3 so as to be driven by vapour from zone 1 and feed its exhaust to zone 3. The engine preferably has a control system (valve 7) which controls the level of the liquid in the evaporator. Additionally, means (valve 25) may be provided for regulating the vapour flow to the motors so that the supply is adequate for the motor 5 for the liquid circulating pump irrespective of the demand by the motor 6 for the fan or other auxiliary equipment. The pump 4, operated by a positive displacement motor which is capable of reciprocating at low frequencies and which will avoid stopping at dead centre, includes inlet 62 and check valve 63 and outlet 64 and check valve 65 for the refrigerant flow. The pump piston 66 in cylinder 67 is connected to a piston rod 68, which is connected to a power piston 69 in a motor cylinder 70. The piston 69 is screw connected to a valve system 70' by pump piston extension 71'. The system 70' carries a flanged head 71. A valve barrel 72, slidably positioned in the valve cylinder 73, has an elongated cylindrical groove 74 and circular detent grooves 75 and 76 co-operating with a spring loaded detent 77. The valve barrel is pierced with bores 77'. Push-pull spring 78 is connected at one end to the valve barrel 72 and at the other end to spring retainer 81. The high pressure inlet line 32, downstream for the valve 7 is connected to the input at the valve cylinder 73 and the exhaust 14 from the pump is connected to the valve cylinder as shown. A by-pass is provided at 79 connecting the grooved space 74 with the space 70 of the power cylinder.
