Controlling compressed air fed to cylinder of compressed air operated piston engine involves trigger on shaft passing contact device once per revolution, causing contact device to open valve

摘要

The method involves enabling and blocking the transport of compressed air to the cylinder with an electrically operated valve connected to at least one contact device via which it is opened and closed. A trigger (15) on the shaft (6) passes the contact device (17) once per revolution and causes the contact device to temporarily open the valve. Independent claims are also included for the following: an arrangement for controlling the compressed air feed for a cylinder of a piston engine operated by compressed air.
