Title: Control apparatus for an internal combustion engine
IPC: F02D11/06
Filed: 1977-05-30
Abstract: The reversing device has a double-acting working piston (4) which is connected to a control shaft (1), for example of a marine diesel engine. This working piston (4) is movably arranged in a sliding cylinder (3), the pressure chambers (14, 15) of which on both sides of the working piston (4) are each connected to a pressure vessel (7, 8) provided with an oil filling, which vessels in turn can be connected by way of a remotely controllable control valve (9) to a compressed air line (12). According to the object of the invention, mechanical locking of the control shaft (1) is to be avoided on reversing of the engine whilst nevertheless ensuring a high degree of reliability and freedom from maintenance. This is achieved in that the pressure vessels (7, 8), in order to maintain a defined pressure acting on the working piston (4), can also be connected to a hydraulic oil line (36), controlled by means of a non-return valve (37) opening at a certain pressure, and are each provided with an outlet orifice (32, 33) having a restrictor (34, 35), about which orifice the level of the oil filling fluctuates. In this way hydraulic locking of the reversible control shaft (1) is provided by simple means. <IMAGE>
