Abstract
In a motor brake for an internal combustion engine having an exhaust valve and an operating mechanism for opening and closing the exhaust valve, the operating mechanism includes a support structure which is firmly connected to, or part of, the internal combustion engine and a pressure element and a valve opening element are movably supported by the support structure so as to transfer a valve opening force to the exhaust valve and a stop structure is provided on the support structure for engaging and supporting the pressure element when the exhaust valve is in the normally closed position or opened for engine braking operation.
Claims12
A motor brake for an internal combustion engine having an exhaust valve (2) and an operating mechanism (1) for opening and closing the exhaust valve (2), said operating mechanism (1) including a support cylinder (5) firmly connected to, or being part of, the internal combustion engine, a pressure piston (11) movably supported in the support cylinder (5) and a valve opening piston (10) also movably supported in the support cylinder (5) between the pressure piston (11) and the exhaust valve (2) for transmitting the valve opening force from the pressure piston (11) to the exhaust valve (2), said hydraulic piston (10) including a bore (16) and the pressure piston (11) including a lug (14) received in the bore of the hydraulic piston (10), said valve opening piston (10) and said pressure piston (11) being supported in the hydraulic cylinder (9) so as to be axially movable relative to each other.
