Abstract
The utility model relates to a control valve for a displacement-changing rotation inclined disk type compressor, which comprises an electromagnetic driving mechanism (1), an upper valve body (8), a bellows (6) arranged on the external end in the upper valve body (8), and a pretightening force adjusting device (6) and a filtering device (5) for the bellows, wherein, the pretightening force adjusting device (6) for the bellows is fixedly connected in a port of the upper valve body (8) arranged on the external end of the bellows (6); the filtering device (5) is annularly arranged on an inlet of an air exhaust cavity (4) arranged on the upper valve body (8). The utility model increases the pretightening force adjusting device for the bellows in an electric control valve; the initial position of the bellows can carry out micro-adjustment conveniently; control points are difficult to generate offset after obtaining vibration or collision in the process of use, and meanwhile, the filtering device (i.e. an anti-clogging structure) is addiionally arranged on one side of a through air exhaust mouth of the electric control valve, and thereby, impurities in the gas can be effectively filtered; the structure of the filtering device and the valve body is compact; complicated machining technology brought by installing a filter screen by drilling on a back cover of the compressor can be avoided, and cost is reduced.
Description
Technical field
The utility model relates to the variable displacement rotary slope plate type compressor that is used for Vehicular air-conditioning apparatus, by the control of electrically-controlled valve, regulates compressor output discharge capacity.
Background technique
Existing variable displacement rotary slope plate type compressor control valve is by the valve gap of the valve body interference fit of adjustment and electrically-controlled valve and the relative axial position between the upper valve body, adjust the pretightening force of bellows, thereby the size of the suffered active force of valve rod in the change electrically-controlled valve is finally adjusted the pretightening force setting value at control point.In addition, cause air-conditioning system for fear of taking place impurity to stop up and break down in system, the dress filter screen that punches on the compressor bonnet usually comes the impurity in the filtering gas.
The control valve of said structure often is difficult to the small adjustment of bellows pretension masterpiece, and especially after electrically-controlled valve is vibrated or collided, problem such as is departed from easily in the control point.In addition, the mode of punching dress filter screen on the compressor bonnet makes the processing technology complexity, and cost is higher.
The model utility content
The purpose of this utility model is to provide a kind of variable displacement rotary slope plate type compressor control valve, this electrically-controlled valve can be carried out the adjustment of trace very easily to the initial position of bellows, especially in use vibrated or collide the back control point be not easy to be offset, reduce the cost of anti-blocking facility simultaneously.
A kind of variable displacement rotary slope plate type compressor control valve provided by the utility model, comprise electromagnetic drive mechanism, upper valve body and be positioned at the bellows of upper valve body outer end, it is characterized in that: it also comprises bellows pretightening force regulating device and filtrating equipment, and described bellows pretightening force regulating device is fixedly connected on the upper valve body port that is positioned at the bellows outer end; Described filtrating equipment ring is located in the exhaust cavity import on the upper valve body.
Above-mentioned variable displacement rotary slope plate type compressor control valve, wherein, bellows pretightening force regulating device is that one one end is provided with an adjustment piece that central authorities are with holes.
Above-mentioned variable displacement rotary slope plate type compressor control valve, wherein, filtrating equipment is to be support with the skeleton that high temperature resistant nylon is done, and is fixed in the exhaust cavity import on the upper valve body by the little snap close on the nylon support.
Owing to adopted above-mentioned technical solution, promptly in electrically-controlled valve, increase bellows pretightening force regulating device, can carry out the adjustment of trace easily to the initial position of bellows, and in use be vibrated or collide afterwards that the control point is not easy to be offset.Simultaneously, side at the logical relief opening of electrically-controlled valve has increased filtrating equipment (being anti-blocking structure), the impurity in the filtering gas effectively, and the compact structure of it and valve body, avoid the complicated processing technology that punching dress filter screen brings on the compressor bonnet, greatly reduce cost.

Fig. 2 is the filter structure schematic representation of the utility model variable displacement rotary slope plate type compressor electrically-controlled valve.
Embodiment
As shown in Figure 1, the utility model variable displacement rotary slope plate type compressor control valve comprises electromagnetic drive mechanism 1, upper valve body 8, is positioned at bellows 6, bellows pretightening force regulating device 6 and the filtrating equipment 5 of upper valve body 8 outer ends.
Bellows pretightening force regulating device 6 is that one one end is provided with an adjustment piece that central authorities are with holes, is threaded in upper valve body 8 ports that are positioned at bellows 6 outer ends.
Filtrating equipment 5 is to be support with the skeleton that high temperature resistant nylon is done, and is fixed in exhaust cavity 4 imports on the upper valve body 8 by the little snap close on the nylon support.
The utility model is provided with the valve body that switches on and off 10 of a control exhaust cavity 4 and crankshaft cavity 3, and the aperture of this valve body 10 is controlled jointly by electromagnetic coil 1 and bellows 6.Bellows 6 is in the air aspiration cavity 7, its end is provided with an adjustment piece 9 that central authorities are with holes, adjust piece and upper valve body 8 to be threaded, can regulate the amount of being screwed into of adjusting piece by certain instrument, thereby can regulate the pretightening force of bellows, bellows is experienced the active force that valve rod 2 is produced behind the pressure of inspiration(Pi) direction, electromagnetic drive mechanism 1 produces another rightabout active forces to valve rod 2 after with certain electric current, the made decision aperture of valve body 10 of the acting in conjunction that acts on the power that the valve rod cross section produces at bellows power, electromagnetic force, spring force and gas.Pass to predetermined electric current at electromagnetic drive mechanism 1, air aspiration cavity 7 passes to the gas pressure of regulation, regulate to adjust the amount of being screwed into of piece, thereby determines the control point of electrically-controlled valve, will adjust on the primary position that piece is fixed on this regulation with screw-threaded coupling glue or resin then.
Exhaust cavity 4 imports in electrically-controlled valve are provided with a filtrating equipment 5 that prevents that impurity from stopping up, the skeleton that this filtrating equipment is done with high temperature resistant nylon is support, this filter screen firmly can be fixed in exhaust cavity 4 imports on the upper valve body 8 by the little snap close on the nylon support.Thereby the exhaust side gas that flows into is filtered, stop up to prevent valve body.
