Title: Cooling device
Inventor: EMI KENJI
IPC: B60H1/00
Filed: 1987-08-28
Abstract: PURPOSE:To ensure the return of lubrication oil to a variable displacement type compressor incorporated in a cooling device for vehicle by using a temperature sensing type expansion valve for a refrigerating cycle expansion valve so as to control the degree of overheat in proportion to a load so that a slight valve opening degree is maintained when a predetermined load is obtained. CONSTITUTION:A temperature sensing cylinder 22 detects the outlet temperature Teo of an evaporator and feeds a pressure PTeo corresponding to the temperature to the upper surface of a diaphragm 71 through an orifice tube 73. Then the opening degree of a valve 75 is determined in accordance with the relationship between a difference between the pressure PTeo and the force of a spring 77, and the inlet pressure Pei (secondary pressure of an expansion valve) of the evaporator. Accordingly, the difference between a saturated temperature Teos with respect to the pressure Pei and the evaporator outlet temperature Teo gives a degree of overheat of coolant so as to control the degree of overheat. Meanwhile the temperature sensing characteristic of the temperature sensing cylinder 72 is set so that the degree of overheat becomes zero at a predetermined load temperature in order to maintain a minimum valve opening degree. With this arrangement, the return of lubrication oil to a compressor in a low load condition is ensured, thereby it is possible to make the operation satisfactory.
