Embodiment Construction
[0018] The compressor used in the refrigeration cycle of the automobile air conditioner is driven by the engine, and the speed of the engine changes according to the movement state of the automobile. The variable capacity compressor with variable refrigerant displacement can obtain sufficient cooling capacity when the engine is idling. Such as figure 2 As shown, in the variable capacity compressor, the main shaft 16 is driven by the engine to drive the hinge mechanism 19 and the swash plate 18 in the crank chamber 15 (the pressure is Pc) to rotate simultaneously. When the swash plate has an angle, the piston 17 reciprocates with the rotation of the swash plate, sucks the refrigerant in the suction chamber 45 (pressure Ps), and discharges it into the exhaust chamber 46 (pressure Pd) after compression, and then discharges it to the air conditioner refrigeration in the loop. The compressor casing is provided with passages 41, 42, 43 to guide the pressure of the suction chamber...

The invention provides an electric control valve. The electric control valve is simple in assembling and is characterized in that a valve chamber is connected with an air exhaust cavity; a valve hole is connected with a crankshaft cavity; a valve assembly is arranged in the valve chamber, the valve assembly comprises a valve and a valve action part, and an flowing area between the valve chamber and the valve hole can be changed when the valve assembly moves; a pressure sensing element and an electric driving element are respectively arranged at two end sides of the valve assembly, a valve connecting part is arranged between the valve assembly and the pressure sensing element, and the outer diameter of the valve connecting part is less than the inner diameter of the valve hole; the valve action part of the valve assembly is coupled with the electric driving element and an action chamber for receiving a driving force from the electric driving element; the valve assembly is internally provided with a middle channel, and the middle channel is connected with an air suction cavity; and one end of the pressure sensing element close to the valve assembly is provided with a clamping part, the clamping part and the inner wall of a shell are in sliding matching, a containing cavity is formed by the clamping part, the shell and the valve connecting part in a surrounding way, the containing cavity is communicated with the middle passageway, and the containing cavity is a second pressure sensing cavity and is used for enabling the pressure sensing element to respond the pressure of the air suction cavity.
Description
technical field [0001] The invention relates to an automobile air-conditioning compressor, in particular to an electric control valve for controlling the displacement of the compressor. Background technique [0002] CN03104307.0 discloses an electric control valve for controlling the displacement of a compressor, such as figure 1 As shown, the first valve housing 2A and the second valve housing 2B are fitted together to form an integrated housing, in which a pressure-sensing chamber 4, a valve hole 5 that is opened and closed, and a valve chamber 6 for accommodating the valve are formed. One end of the pressure-sensing member 22 is fixed in the end cap 3 , and the engaging portion 22B at the other end is slidably engaged with the valve-opening connection portion 30 . The valve-opening connection portion 30 is fixedly connected to the valve 21 and moves together with the valve 21 . An open passage 26 is formed in the middle of the valve 21 , and when the valve 30 is opened, ...
