Abstract
A cylinder head for a compressor includes a closure device that can be adjusted between an unactuated position (off-load) in which the compressor delivers air and an actuated position (off-load) in which the compressor is running in an idle mode, a pneumatic control device having a control cylinder and a control piston that can be moved in the control cylinder, a spring device that prestresses the closure device into the unactuated position (on-load), and a driver configured to couple the control piston to the closure device. The closure device closes a compressed air passage in the unactuated position (on-load) and clears the compressed air passage in the actuated position (off-load), and the driver is permanently connected to the closure device and can be driven by the control piston.
