AUTOMATIC SYSTEM OF PRESSURE CONTROL IN PNEUMATIC SYSTEM OF TRACTIVE TRANSPORT DEVICE Russian patent published in 2011 - IPC F15B7/04 G05D16/00 

FIELD: machine building.

SUBSTANCE: system consists of pneumatic system connected to compressor and of control element of continuous action. A shaft of the compressor is driven to rotation from a shaft of hydro-volumetric engine by means of pipelines communicated with a hydro-volumetric pump, oil filter and oil tank. The hydro-volumetric pump, shaft of which is driven from the shaft of a heat engine by means of a pipeline, is connected with an oil cooler tied in its turn with the oil filter and oil tank by means of the pipelines. The control element of continuous action corresponds to a unilateral membrane spring drive equipped with an adjusting nut. A rod of this drive is connected with a distributing washer of the controlled hydro-volumetric pump, while a membrane chamber is connected with the pneumatic system of the tractive transport device by means of the pipeline.

EFFECT: improved quality of operation of pressure control system.
