Abstract
The utility model discloses an electric variable valve, comprising a shell, a coil base, an iron core, a valve base and a pressing cap. The coil base is mounted in the shell; a guide sleeve is sleeved in the coil base; an ejector rod base and the iron core are arranged in the guide sleeve; an ejector rod passes through the iron core; one end of the ejector rod is abutted against the ejector rod base, and the other end of the ejector rod is abutted against a push rod in the valve base; a resetting spring is mounted at one end of the push rod, which is abutted against the ejector rod; the other end of the push rod is abutted against a corrugated pipe mounted in the valve base; a spring is sleeved at one end of the push rod, which is abutted against the corrugated pipe; the pressing cap is fixedly connected with the valve base; a fastening ring is arranged between the shell and the iron shell; and the guide sleeve is connected with the shell in a sealed manner. The electric variable valve provided by the utility model has the advantages of simple process and low machining difficulty.
Description
Technical field
The utility model relates to a kind of automobile air conditioner compressor and uses accessory, relates in particular to the electronic variable valve that a kind of car air conditioner positive displacement compressor is used.
Background technique
In the existing technology, guide sleeve and housing are to weld together, and are integral structures, complex process, and difficulty of processing is big.
Summary of the invention
The purpose of the utility model is to provide the electronic variable valve that a kind of technology is simple and difficulty of processing is low.
In order to achieve the above object, the technological scheme of the utility model is: a kind of electronic variable valve comprises housing, coil base, iron core, valve seat and pressure cap; Hookup wire ring support in the said housing is set with guide sleeve in the coil base, have tip-lever support, push rod and iron core in the guide sleeve; Push rod passes an iron core and an end and tip-lever support and offsets; The other end of push rod and the push rod in the valve seat offset, and the end that said push rod and push rod offset is equipped with Returnning spring, and the other end of push rod offsets with the bellows that is contained in the valve seat; And an end that offsets with bellows of push rod also is set with spring; Pressure cap is fixedly connected with valve seat, has tight fixed ring between said housing and the iron core, and its innovative point is: said guide sleeve and housing seal load.
Has seal ring between said housing and the guide sleeve.
After adopting said structure, because guide sleeve and housing seal load, guide sleeve and housing are splits when that is to say work, but not one, so welding processing difficulty of processing than before is low, technology is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.
As shown in Figure 1, a kind of electronic variable valve of the utility model comprises housing 1, coil base 2, iron core 4, valve seat 6 and pressure cap 12; Hookup wire ring support 2 in the said housing 1 is set with guide sleeve 3 in the coil base 2, have tip-lever support 7, push rod 8 and iron core 4 in the guide sleeve 3; Push rod 8 passes an iron core 4 and an end and tip-lever support 7 and offsets; Push rod 10 in the other end of push rod 8 and the valve seat 6 offsets, and said push rod 10 is equipped with Returnning spring 9 with the end that push rod 8 offsets, and the other end of push rod 10 offsets with the bellows 11 that is contained in the valve seat 6; And an end that offsets with bellows 11 of push rod 10 also is set with spring 18; Pressure cap 12 is fixedly connected with valve seat 6, has tight fixed ring 5 between said housing 1 and the iron core 4, said guide sleeve 3 and housing 1 sealing load.
Has seal ring 13 between said housing 1 and the guide sleeve 3.
The utility model is owing to guide sleeve and housing seal load, and guide sleeve and housing are splits when that is to say work, but not one, so welding processing difficulty of processing than before is low, technology is simple.
