FIELD: machine building.
SUBSTANCE: pneumatic-hydraulic actuator includes a high pressure gas bottle, a startup pyrovalve, a pressure control, a pneumatic-hydraulic pressure transfer device to actuators, a temperature compensation device and a liquid discharge device, which are connected via pipelines. Pneumatic-hydraulic pressure transfer device is made in the form of a row of pneumatic-hydraulic cylinders. Each of the above pneumatic-hydraulic cylinders is connected to the corresponding pressure control. The above pressure controls are combined by means of a common header. The above header is connected to the temperature compensation device. The latter includes a cylindrical housing with a shell with elastic bellows installed inside it. The above bellows are made in the form of an elastic element with a breakthrough liquid discharge end wall.
EFFECT: reduction of weight and dimensions of a pneumatic-hydraulic actuator.
