    摘要: A thermal expansion valve for automotive coolant systems which is significantly more compact than previously developed expansion values. The housing of the expansion valve is divided into a first housing formed in a cylindrical shape with a bottom and a second housing formed in a columnar shape. The first housing is fit into the second housing, and both are integrally connected to each other. A temperature sensing mechanism having a temperature sensing chamber and an expansion mechanism for adjusting an opening degree of a throttle passage in accordance with an evaporator outlet temperature sensed by the temperature sensing means are disposed in the second housing. First and fourth joint portions connected to inlet and outlet refrigerant pipes of the evaporator, respectively, are at the bottom of the first housing. On the other hand, second and third joint portions connected to a compressor suction side refrigerant pipe and a high-pressure side refrigerant pipe from a receiver, respectively, are at an outer surface of the second housing. In this manner the overall size of the expansion valve is reduced considerably, thus saving valuable space in an engine compartment of a vehicle.

    摘要: A centrifugal type separator is disposed on a downstream side of a temperature-operating type expansion valve. Liquid-phase refrigerant separated herein is again pressure-reduced by an aperture resistance and thereafter inducted to an inlet side of the evaporator by means of a liquid-phase refrigerant discharge passage. Meanwhile, gas-phase refrigerant separated by the separator is returned directly from a gas-phase refrigerant discharge passage to an evaporator outlet side passage, and after being united with superheated gas-phase refrigerant evaporated by the evaporator, is taken into a compressor. A temperature-sensing tube of the expansion valve is disposed further on the downstream side of the foregoing union location so as to enable the temperature of the superheated gas-phase refrigerant evaporated by the evaporator to be sensed accurately.

    摘要: According to the present invention, a thermal expansion valve for a refrigerating cycle includes a housing having a throttle passage therein for expanding the refrigerant thereinto from the high-pressure side liquid refrigerant circuit, a valve element provided within the housing for adjusting opening degree of the throttle passage, and a thermosensitive element movably disposed within the housing. The thermosensitive element includes a case and a pressure responding member disposed within the case and displacing according to temperature and pressure of the refrigerant at the exit of an evaporator. The case of the thermosensitive element is integrally connected to the valve element, and the thermosensitive element and the valve element are so constructed as to integrally move according to the displacement of the pressure responding member. Accordingly, even if the valve element vibrates due to the sharp expansion of the refrigerant and the vibration transmits to the thermosensitive element case, as the thermosensitive element case is movable with respect to the housing and the housing are separated from the thermosensitive case, most of the vibration is prevented from being transmitted to the housing.
