Изобретение относитс к системам регулировани давлени воздуха в пневматичгской сети путем разгрузки компрессора и может быть использовано в производстве колесных транспортных средств, оборудованных пневматическим приводом тормозов и компрессором в качестве источника сжатого воздуха.The invention relates to air pressure control systems in a pneumatic network by unloading a compressor and can be used in the manufacture of wheeled vehicles equipped with pneumatic actuated brakes and a compressor as a source of compressed air.

Известны регул торы давлени , предназначенные дл разгрузки компрессора при достижении в сети уплотнительные элементы l .Pressure regulators are known for discharging a compressor when the sealing elements l are reached in the network.

Такие регул торы не обеспечивают четкую, разгрузку компрессора при достижении в сети заданного давлени Such regulators do not provide a clear, unloading of the compressor when the network reaches the specified pressure

Наиболее близкий к предлагаемому по технической сущности вл етс регул тор давлени дл разгрузки компрессора , содержащий корпус с отверсти ми дл подвода рабочего тела от пневматической сети и отвода его к разгрузочному устройству компрессора, и размещенный в нем подпружиненныйClosest to that proposed by the technical entity is a pressure regulator for unloading a compressor, comprising a housing with openings for supplying the working fluid from the pneumatic network and diverting it to the compressor unloading device, and the spring loaded therein

ПОДВИЖНЫЙ поршень с манжетой, имеющей уплотнительную кромку С2.MOVING piston with a cuff having a sealing edge C2.

Однако такой регул тор давлени слоиген по конструкции.However, such a pressure regulator is slegigen by design.

Цель изобретени - упрощение конструкции регул тора давлени .The purpose of the invention is to simplify the design of the pressure regulator.

Поставленна цель достигаетс тем, что ось отверсти дл подвода рабочего тела к разгрузочному устройству расположена в зоне между The goal is achieved by the fact that the axis of the hole for the supply of the working fluid to the discharge device is located in the area between

to крайними положени ми уплотнительной кромки манжеты, а диаметр этого отверсти не превышает ширину уплотнительной кромки.to the extreme positions of the sealing lip of the cuff, and the diameter of this hole does not exceed the width of the sealing lip.

Claims

The controller comprises a housing 1 with an opening 2 for supplying a working fluid from the pneumatic network and an opening. 3 for removal of the working fluid to the unloading device of the compressor, a cover i with an opening 5 for connection to the atmosphere. Between the cover k and the housing 1, a movable piston 6 390 with a cuff 7 mounted on it is placed, spring-loaded by an adjusting spring 8 supported by the upper face on the adjusting bolt 9 through the plate 10. The cuff 7 has a sealing edge 11. The regulator works as follows. When the compressor is operating under load, the pressure in the pneumatic net increases. As the hole 2 is further compressed with the pneumatic net, the pressure in the piston cavity also increases. The force of the spring 8 by means of the bolt 9 is adjusted in such a way that when the specified pressure in the hole 3 is set, the piston 6 together C-. the cuff 7 is moved upward, while sealing onto the edge 11 of the cuff 7 will be placed above the opening 3 and the compressed air from the pneumatic network through straps 2 and 3 enters the compressor discharge unit and switches the compressor to idle mode, after which the further flow of compressed air into the pneumatic network is stopped. As the compressed air is consumed, the pressure in the pneumatic network drops, as a result of which, the pressure in hole 2 and in the piston cavity also decreases. When Ds13leni drops a certain size, the spring 8 moves the pores I of the Šen 6 from the cuff: 7 to the lower position, with the sealing edge 11 of the cuff 7 being below the hole 3 | as a result, the opening 3 is separated from the opening 2 and communicates with the over-piston cavity connected through the opening 5 to the atmosphere, and the compressed air from the discharge device through the opening 3, the above-piston cavity and opening 5 goes to the atmosphere, after which the compressor starts to operate again under load and supply compressed air to the pneumatic network. The use of the proposed pressure regulator will significantly reduce the range of parts and reduce the labor intensity of manufacturing due to simplified design. Invention A pressure regulator for discharging a compressor, comprising a housing with openings for supplying a working fluid from a pneumatic network and discharging it to a compressor unloading device, and a spring-loaded movable piston with a cuff having a sealing lip, characterized in that simplify the construction, the axis of the hole for supplying the working fluid to the discharge device is located in the zone between the extreme positions of the sealing edge of the cuff, and the diameter of this hole does not exceed the width Rinu sealing edge.
