    Abstract: In a thermostatic expansion valve included in a refrigeration cycle for expansion of a refrigerant which is contained in the refrigeration cycle, the thermostatic expansion valve is provided with a particular chamber (14) which is substantially separated from a refrigerant passage (10, 11) for guiding the refrigerant and is connected to the refrigerant passage through an additional passage (15). The particular chamber has pressure relating to pressure in the refrigerant passage when the refrigeration cycle is operated. In order to reduce influence of the pressure in the refrigerant passage, a pressure transmission member (22) transmits the pressure in the particular chamber to a valve mechanism (200a, 201) which is placed in the refrigerant passage to adjust a flow of the refrigerant in the refrigerant passage. An operation control arrangement (205, 206, 207) controls an operation of the valve mechanism in response to temperature of the refrigerant.

    Abstract: A slant plate type compressor with a variable displacement mechanism is disclosed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each cylinder and is reciprocated by a drive mechanism including a slant plate having a surface with an adjustable inclined angle. The inclined angle is controlled by the pressure within the crank chamber to control the capacity of the compressor. The pressure in the crank chamber is further controlled by a control mechanism which includes two passageways linking the crank chamber with the suction chamber, each passageway having a valve control device to control the opening and closing of the passageway. The first valve control device controls the first passageway in response to the suction chamber pressure at a third control point. The second valve control device controls the second passageway in response to the suction chamber pressure at a first control point and at a second control point such that the passageway is open when the pressure exceeds the second control point and the passageway is closed when the suction pressure is below the first control point. The first control point is less than the third control point which is less than the second control point. The second valve control device includes a deformable plate hysterically responsive to the suction chamber pressure to switch between two shapes to control the link.

    Abstract: A variable displacement compressor includes a suction chamber, a discharge chamber, and a crank chamber. The compressor also includes a first path for allowing communication between the crank chamber and the discharge chamber, and a second path for allowing communication between the crank chamber and the suction chamber. Moreover, the compressor includes a valve assembly. The valve assembly includes a valve positioned within the first path, and the valve assembly controls a pressure in the crank chamber by varying a position of the valve. The compressor also includes an orifice mechanism. The orifice mechanism includes a plate having a hole formed therethrough, and an elongated member positioned within the hole. Specifically, the elongated member is movable within the hole, and an annulus of the orifice mechanism is defined between the elongated member and an interior surface of the hole. Moreover, the annulus defines a portion of the second path, and the orifice mechanism controls a flow of a refrigerant from the crank chamber to the suction chamber by varying an area of the annulus. The compressor also includes a linking member operationally coupling the valve assembly to the orifice mechanism. For example, the linking member may operationally couple the valve assembly to the orifice mechanism, such that when the area of the opening of the annulus is at a minimum area, the valve may be open, and when the area of the opening of the annulus is at a maximum area, the valve may be closed.
