Abstract
A variable compressor electric control valve comprises a shell, a coil base, a lead wire, a spring, a valve base, a push rod, a corrugated pipe, a sealing ring and the like, wherein a steel ball is arranged at the upper end of a push rod, and the steel ball and the push rod are arranged on the same straight line; the valve body is provided with a curved surface, and the axis of the curved surface of the valve body is collinear with the axis of the steel ball. The curvature radius of the push rod and the steel ball, and the curvature radius of the valve body are consistent with the radius of the ball. Thereby ensuring the seal of the top with the valve seat. The utility model discloses to joining in marriage different air conditioning system, need not change the control valve of compressor, as long as change control procedure, have the centralized control that can realize whole car, realize that zero discharge volume starts, reduce the impact to the engine, high speed state subtracts advantages such as discharge capacity, the reliability increase of compressor.
Description
Technical field:
The utility model relates to the electric control valve of variable compressor that is used for Vehicular air-conditioning apparatus, by the regulating and controlling compressor output discharge capacity of this electrically-controlled valve.
Prior art:
Existing positive displacement compressor adopts the bellows in the Pneumatic valve to experience the pressure of compressor air suction chamber Ps, exhaust cavity Pd usually, regulates the crankshaft cavity internal pressure P of compressor
oThereby, change the equilibrating force system of compressor piston swash plate mechanism, and then change compressor swash plate angle, compressor displacement is changed.But the compressor of this structure is difficult to realize zero delivery, the easy frosting of system, and control is slow, realization increases/fall the stroke difficulty.
And existing automatically controlled rule employing is the mode of inlet control.This control mode need be controlled the gas circuit between hyperbaric chamber and crankshaft cavity, because pressure reduction is big, realizes the sealing difficulty, makes the requirement on machining accuracy height, and the processing technology complexity causes manufacture cost to improve.
Shanghai is " variable displacement rotary slope plate type compressor electrically-controlled valve " (number of patent application: 02155160.X) of Meccanica Generale S. R. L's invention just easily.It comprises the connector assembly of electromagnetic drive mechanism, valve body, following valve body, upper valve body, bellows, pretightening force regulating device, filter screen and lighting outlet, described electromagnetic drive mechanism is arranged on down in the valve body, and it comprises moving iron core and the static iron core that is provided with in the middle of electromagnetic coil, Returnning spring, the coil; Described upper valve body and following valve body are involutory, form crankshaft cavity and air aspiration cavity on upper valve body, and described valve body is arranged between crankshaft cavity and the air aspiration cavity, and is provided with the regulating device of valve body, bellows and bellows pretightening force in upper valve body; Described filter screen ring is located at the crankshaft cavity place, and the terminal of the electromagnetic coil in the connector assembly of lighting outlet and the described electromagnetic drive mechanism link to each other.The side of the moving iron core in the electromagnetic drive mechanism has air vent or hole.Owing to adopt above-mentioned technical solution, the outlet of low voltage side can be adjusted and realize control, makes the pressure control of crankshaft cavity more steady, thereby makes the displacement variation of compressor more stable.But the outlet of low voltage side can't be adjusted during practical operation, can not solve the sealing of spool.
Goal of the invention:
The purpose of this utility model is to provide a kind of positive displacement compressor electrically-controlled valve, and it can not only overcome above-mentioned defective, realizes centralized control, has solved the seal spool problem simultaneously.
Summary of the invention:
A kind of positive displacement compressor electrically-controlled valve provided by the utility model, form by housing, coil base, lead-in wire, spring, valve seat, push rod, bellows, seal ring etc., it is characterized in that being provided with steel ball in the push rod upper end portion, steel ball and push rod axis are on same straight line; Valve body is provided with curved surface, valve body curved surface axis and steel ball axis conllinear.The radius of curvature that push rod and steel ball connect, valve body the radius of curvature and the radius of ball consistent.Thereby guarantee the sealing of top and valve seat.
Beneficial effect:
The utility model compared with prior art, good sealing effect has simple in structure, reliable operation and advantage such as easy to use.
