Pneumatic pressure-transmitting actuator with fast- and power-stroke - has low- and high-pressure component of equal dia.

摘要

The high pressure component consists of a cylinder (7), a piston (1) with seals (4), shock absorber rings (5,9,19) and a non-return valve (20) inside the supply port (10 E). The low pressure component consists of the cylinder barrel (12), the cylinder cap with tie rods (22), a piston with seals (15) and shock absorber rings. Compressed air passes through the supply port (10 E) to the high pressure cylinder (7) and moves the piston to the right. During the return stroke, the piston moves to the left at high speeds and compresses the air inside the cylinder thus generating the required forces for the power stroke. USE - In drives of die- stamp- and punching- machines and in clamping devices.
