Throttle device for small liquid mass flows in the range of the boiling state

The invention relates to a device for throttling liquids, when these are relieved to low pressure in the range of the boiling state, as is the case in cold and heat pump cyclic processes. If there are installations with small liquid circulation flows, screens, nozzles or capillary tubes are preferred, which, however, as a result of throttling vapour arising, demonstrate unstable behaviour or block when the liquid undercooling is not sufficient. The device according to the invention allows a stable relief process in the throttling member by the liquid to be relieved being undercooled by an upstream heat exchanger before the pressure reduction takes place in the throttling member, cooling being carried out with the entire liquid relieved to low pressure, which at the same time partially evaporates. The cooling capacity is not lost to the cyclic process because, as a result of the undercooling, a correspondingly larger evaporation enthalpy is available. The arrangement shown in the diagram ...

Improvements in and relating to pressure reducing devices

... 709,617. Valves. GENERAL ELECTRIC CO. Oct. 17, 1952 [Oct. 19, 1951], No. 26096/52. Class 135 A pressure reducing valve for maintaining a desired pressure differential between the high and low temperature evaporators of a refrigerating system, comprises a casing 8 having a partition member 11 having an axial bore 13 loosely mounting a valve pin 16 to permit equalization of pressure on opposite sides of the member.

Refrigerant then flows through the slot 14 to act on the upper side of the plunger to resist its upward movement and so delay the full opening of the valve. Downward movement of the plunger is delayed by the slow leakage of refrigerant ...

Ejector cycle and arrangement structure thereof in vehicle

In an ejector cycle having an ejector, a throttle is provided inside a passenger compartment adjacent to an evaporator so that a length of a refrigerant passage between the throttle and the evaporator is shortened. Therefore, it can restrict a part of liquid refrigerant after being decompressed in the throttle from being evaporated in the refrigerant passage, before being introduced into the evaporator. In addition, a refrigerant inlet is provided at a lower header tank of an evaporator. Therefore, a gas-liquid refrigerant distribution difference due to the density difference between gas refrigerant and liquid refrigerant can be effectively restricted. Thus, refrigerant distributed into the plural tubes from the lower header tank can be made uniform, even if the refrigerant flow speed is low in the ejector cycle.
