Description
Technical field:
The present invention relates to be used for the electric control valve of variable compressor of Vehicular air-conditioning apparatus, particularly a kind of motor-operated control valve of positive displacement compressor is exported discharge capacity by the regulating and controlling compressor 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.
I once designed the electric control valve of variable compressor (patent No.: 200720131724.5), improve the technical performance of original electrically-controlled valve greatly, but in the processing of reality, had the matching problem of a kind of former tip-lever support and guide sleeve, required precision is very high, is easy to occur the situation of useless part.
Goal of the invention:
The object of the present invention is to provide a kind of positive displacement compressor electrically-controlled valve, it can not only realize centralized control, has solved more reliable performance that the difficulty of processing problem makes this electrically-controlled valve, feasible simultaneously.
Summary of the invention:
A kind of electric control valve of variable compressor, form by housing, coil base, guide sleeve, tight fixed ring, valve seat, push rod, spring, push rod, bellows, seal ring etc., guide sleeve and tight fixed ring have been installed in housing, guide sleeve and tight fixed ring cooperate with the iron stamen, be provided with push rod in the iron stamen, the shaft axis conllinear of the shaft axis of push rod and valve seat, spring II and push rod, its medi-spring II is in tip-lever support, push rod cooperates with bellows, thereby guarantees the sealing of top and valve seat by the two-way function of spring II.Have several gas ports on the end face circumference of tip-lever support conical surface end, the size of gas port depends on the size of Throughput, and gas port communicates with the macropore of mounting spring I.The front-end face of iron stamen and tip-lever support conical surface end face match, and when push rod promotion tip-lever support moved, the front-end face of iron stamen separated with tip-lever support conical surface end face, and gas enters the macropore of mounting spring I by the hole on the end face circumference of tip-lever support conical surface end.
Beneficial effect:
Because spring I and the back-to-back installation of spring II, thereby guarantee relative position between each part, guaranteed sealing effect.Because iron stamen and tip-lever support are divided into two parts, have improved processing technology.Gas port is arranged on the end face of tip-lever support, has improved the processing technology of tip-lever support, has improved the sealing effect between tip-lever support and the guide sleeve simultaneously.The present invention compared with prior art, sealing effect is better, structure is simpler, work is more reliable and process advantages such as more convenient.
