Description
Technical field
The utility model relates to automobile air conditioning technology field more particularly to a kind of shaking tray Control Valve in Variable Displacement Compressor.
Background technique
Shaking tray variable compressor is one of current compressor state-of-the-art in the world, it has energy conservation, fuel-economizing, automobile fortune
Turn many advantages, such as steady, is just developed rapidly in every field.Common control valve failure is ripple in the previous use of the compressor
Compressor small displacement works after tracheal rupture, and air-conditioning system is caused to fail.
Utility model content
The utility model will solve the above-mentioned problems of the prior art, provide a kind of shaking tray variable compressor control
Valve leads to compressor fault after solving the problems, such as current bellows bursts, meets the needs of compressor.
The utility model solves the technical solution of its technical problem use: this shaking tray Control Valve in Variable Displacement Compressor, packet

It is provided with bellows, the junction of valve rod and valve seat is provided with ball valve, and ball valve is arranged in valve seat, the junction of valve rod and ball valve
It is provided with taper platform, the setting of taper platform is provided with sealing valve port on valve rod, on valve seat, and sealing valve port is located at the one of taper platform
Side.
Shell is provided on valve body, bellows is located in shell.
Sealing ring is provided on valve seat.
The utility model has the advantages that: the shaking tray Control Valve in Variable Displacement Compressor of the utility model, structurally reasonable, energy
The work of compressor small displacement causes air conditioning for automobiles to fail after enough solving the problem of bellows bursts, can after bellows bursts
Compressor is set to have been at huge discharge working condition, air-conditioning system can be used normally, and avoid failure, and using effect is good,
Conducive to popularization.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Description of symbols: valve body 1, valve seat 2, valve rod 3, bellows 4, ball valve 5, taper platform 6, sealing valve port 7, shell 8,
Sealing ring 9.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to attached drawing: this shaking tray Control Valve in Variable Displacement Compressor in the present embodiment, including valve body 1 are provided on valve body 1
Valve seat 2 is provided with valve rod 3 in valve body 1, and one end of valve rod 3 is arranged on valve seat 2, and the other end of valve rod 3 is provided with bellows 4,
The junction of valve rod 3 and valve seat 2 is provided with ball valve 5, and ball valve 5 is arranged in valve seat 2, and valve rod 3 and the junction of ball valve 5 are provided with
Taper platform 6, taper platform 6 are arranged on valve rod 3, and sealing valve port 7 is provided on valve seat 2, and sealing valve port 7 is located at the one of taper platform 6
Side.
Shell 8 is provided on valve body 1, bellows 4 is located in shell 8.
Sealing ring 9 is provided on valve seat 2.
The variation of shaking tray variable compressor discharge capacity is controlled by control valve, and bellows incudes pressure of inspiration(Pi) variation.When
When car room temperature is low, pressure of inspiration(Pi) is low, bellows elongation, opens ball valve, and high pressure gas enters crankcase, and piston left and right ends generate
Pressure difference reduces shaking tray inclination angle.Conversely, car room temperature is too high, pressure of inspiration(Pi) is higher than control point, and ball valve is closed, and high pressure gas is not
Crankcase is entered back into, on the contrary, shaking tray inclination angle increases, discharge capacity increases the pressure difference direction at piston both ends.The compressor used in the past
In common control valve failure be that compressor small displacement works after bellows bursts, cause air-conditioning system to fail.
To solve this problem, control valve arrangement is adjusted, increases a taper platform 6 in 3 front end of control valve valve rod,
Valve seat 2 increases a sealing valve port 7, and when bellows 4 ruptures, bellows 4 extends, and pushes valve rod 3 to move forward, opens ball valve
5, high pressure gas enters crankcase in order to prevent, and 3 front end taper platform 6 of valve rod seals valve port 7 with valve seat 2 and is bonded.Therefore compressor one
It directly is in huge discharge working condition, air-conditioning system can be used normally, and the failure is avoided to occur.
The characteristics of the utility model embodiment is: compressor small displacement works after being able to solve bellows bursts, leads to vapour
The problem of vehicle air-conditioning fails, can make compressor have been at huge discharge working condition, air-conditioning system can after bellows bursts
With normal use, failure is avoided, using effect is good, is conducive to promote.
Although the utility model is shown and described by reference to preferred embodiment, this profession is common
Technical staff is it is to be appreciated that within the scope of the claims, can make various variation in form and details.
