<p>A compressed air starter including pneumatically operating starting valves for diesel engines, whereby includes one main starting valve connected to the cylinder head of the engine and provided with a valve body, which co-operates with a valve seat in order to alternatively open and close an inlet opening for compressed air to one cylinder, whereby during the start up of the engine, starting air (compressed air) continuously is supplied to the main starting valve, said valve body including one servo piston, which is controlled by servo air from a supply of servo air, which servo air is acting on the servo piston during moments related to the working phase of the engine. The object of the invention is to simplify the pipe arrangement for the compressed air at a diesel engine with several cylinders where it is usually arranged a main distributor for distributing the servo or pilot air, which controls the starting valves. The invention consists of a magnetic valve (17), which is connected to the main starting valve (8, 9, 10) and has a valve slide, which in one position (I-II) connects the supply (16) of servo air with a compression face of the servo valve (10), said servo valve hereby being activated to drive the valve body (8, 9) to the opening position and that, in a second position (II-III) of the valve slide, it controls the outlet from the supply (16) of servo air so that the servo piston drives the valve body (8, 9) to a closing position, said magnetic valve (17) being controlled by electric signals from a transmitter (20) controlled by the crank shaft or by an axis (22) rotating in accordance with the working phase of the engine. </p> |
