Abstract

The utility model relates to a power saving device for the car air compressor, belonging to the car air compressor fitting of the traffic field. The power saving device for the car air compressor is composed of a rocker, a piston, an air-controlled sliding valve, etc. The power saving device for the car air compressor has the function of automatically controlling the operating state of the air compressor according to the internal pressure of the car air compressor. When the inner pressure of the air compressor is higher, the air compressor can be adjusted to stop the operation. When the inner pressure of the air compressor is reduced caused by the reasons of the brake, etc., the air compressor can recover the operation. The service life of the air compressor is prolonged, the pulling power of the engine can be increased, and the effect is great.

Description

Power saving device for car air compressor

The utility model relates to a kind of automobile air compressor economizer, belongs to traffic and transport field automobile air compressor accessory.

The compressed-air brake that most of vehicle adopted in the communications and transportation at present, mainly be to come to supply pressurized air by air compressor, as long as engine start, belt just drives air compressor work, when the pressure of gas receiver will exceed range of regulation, safety valve is outwards exitted, reduce internal pressure, make air pressure be no more than rated load, yet, use device of air on the vehicle, only spend air compressor and supply with a compressed-air actuated part, most pressurized air has all wasted, and at this moment motor is still constantly exported a part of power to air compressor, cause motor to make idle work, also make air compressor do unworthy wearing and tearing.

The purpose of this utility model is exactly in order to address the above problem, but a kind of automatic Regulation is provided, and can make the work of air compressor interruption, thereby improves the life-span of air compressor and increase the economizer of the tractive force of motor.

The purpose of this utility model is achieved in that it is made up of rocking bar, piston, cylinder barrel, gas control guiding valve etc., wherein the gas control guiding valve adopts two-position three way formula structure, be provided with a gas port＜B 〉, a relief opening＜C 〉, the gentle voltage-controlled drilling of a high pressure admission mouth＜A〉＜K 〉, utilize the motion of air pressure guiding valve control piston, when air pressure reaches the setting high pressure, the A mouth and the B mouth of gas control guiding valve communicate, cylinder charge, piston motion, guide pulley leaves drivign belt, belt loosens, and air compressor is not worked; When air pressure was reduced to setting low pressure, gas control guiding valve B and C mouth communicated, the cylinder venting, and piston moves downward under action of reset spring, and this moment, guide pulley compressed belt, and air compressor is reworked, and just forms an economizer of regulating air compressor work automatically.

Description of drawings:

Fig. 1 is an air compressor economizer sectional view.

Wherein: 1. guide pulley, 2. rocking bar, 3. piston, 4. Returnning spring, 5. cylinder barrel, 6. pressure regulating screw, 7. support, 8. guiding valve Returnning spring, 9. hinge frame, 10. gliding mass, 11. valve bodies, 12. gas control guiding valves, 13. piston rods.

Below in conjunction with accompanying drawing the utility model is elaborated:

The utility model provides the economizer of the empty compressor of a kind of automobile, it is made up of rocking bar, piston, cylinder barrel, gas control guiding valve etc., be provided with a piston (3) in the inner chamber of cylinder barrel (5), piston (3) is connected with piston rod (13), the part of piston rod (13) in cylinder barrel (5) is with a Returnning spring (4), this spring at the cylinder internal air pressure hour impels piston to move downward, and makes guide pulley compress belt; The gentle control slide valve of lower end mouth (12) of cylinder barrel (5) is tightly connected, make the bore seal of cylinder barrel (5), it is outer and hinged with rocking bar (2) that piston rod (13) reaches cylinder barrel (5) by the last hole of cylinder barrel (5), one end of rocking bar (2) and support (7) are hinged, the other end and guide pulley (1) are fixing, rocking bar (2) drives the upper and lower motion of guide pulley when the upper and lower motion of piston rod, the degree of tightness of control belt, support (7) is used for supporting crank (2), and it is to be fixed on the valve body (11) of gas control guiding valve (12) by hinge frame (9).

Introduce the gas control guiding valve that adopts in the utility model below, this gas control guiding valve is a kind of one control air valve of two-position three way structure, be by valve body (11), gliding mass (10), guiding valve Returnning spring (8), pressure regulating screws etc. are formed, gliding mass (10) is mounted in the inner chamber of valve body (11), can do horizontal linear reciprocation slides, on valve body (11), be provided with a gas port＜B 〉, gas come in and go out thus cylinder and pressure regulation, a relief opening＜C 〉, the gentle voltage-controlled drilling of a high pressure admission mouth＜A〉＜K〉constitutes a two-position three way structure of being with control end; Pressure regulating screw is fixed on an end of valve body (11) and joins with valve body Returnning spring (8), and gliding mass is resetted, the cylinder venting, and the other end of valve body Returnning spring and gliding mass (10) join, and promote gliding mass and reset.

Compact structure of the present utility model, volume is little, after its machine shaping, directly install and get final product, and need not to carry out the change of other device, the tractive force that can improve locomotive behind the utility model is installed simultaneously, be original two to three times working life that prolongs air compressor, of far-reaching significance.
