Abstract

A device used for pneumatic control, includes a control piston carried in a cylinder. The control piston is mounted so as to be movable in the direction of a longitudinal piston axis, and a primary flow path that can be closed by the control pressure passes through the cylinder. The control piston is provided with a control surface that faces a control chamber of the cylinder and that is designed to transmit a control force to the control piston. The control piston is made at least partially of a plastic.
