Abstract: A valve to provide a controlled loss of hydraulic fluid from a closed loop hydrostatic transmission. A method of converting a bleed-off valve from one sensitive only to loop pressure to one sensitive to both loop pressure and charging line pressure. A pressure sensitive surface in flow communication with charging line pressure is used to position the valve to shut off flow in the event that charging line pressure is lost. In the event that charging line pressure and loop pressure are normal the valve provides a controlled bleed of hydraulic fluid. Finally, in the event that loop pressure becomes unacceptably high, flow is shut off.

Abstract: The refrigerating apparatus for a load in a coolant bath has a buffer tank which is maintained at a low pressure via a vacuum pump. The buffer tank communicates via a valve with a vapor chamber above the coolant bath. Upon an increase in heat evolution from the load above the rating of the compressor, the pressure in the vapor chamber causes the valve to open and excess vapor to escape into the buffer tank. The pressure in the vapor chamber thus remains constant while the temperature of the load does not increase.

Abstract: Scavenging is applied to a conventional refrigeration cycle to return most of the energy normally remaining in a warm condensed liquid to the cycle. This permits considerably more energy to be picked up in the evaporator of the cycle than under conventional practice. The concept is applicable to any type positive displacement compressor where an intake of evaporator generated gas can be trapped in the compressor, with the scavenged gas then added prior to mechanical compression. The concept is particularly applicable to reciprocating compressor type heat pump systems.
