In a clearance compensating device for an internal combustion engine with an internal part movably arranged within a guide duct of an external part for adjusting a clearance of an associated valve of the internal combustion engine, a pressure chamber, and a storage chamber which is hydraulically connected to the pressure chamber for receiving hydraulic fluid are associated with the interior part. Between the two chambers a one-way valve is disposed for applying an actuating force to the interior part relative to the external part. A feeding device is hydraulically connected to a blocking chamber for supplying a hydraulic fluid to the blocking chamber in order to exert a blocking force to the internal part acting in a direction opposite the actuating force under the control of a timing device the blocking force being modified depending on a cycle of the timing devices.

Valve clearance compensation device and method for controlling a valve clearance compensating device for an internal combustion engine

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.

Motorbrake for an internal combustion engine

In a valve timing gear for an internal combustion engine having valves, means for actuating the valves and oil supply passages for supplying lubricating oil to the valve actuating means, the oil supply passages have side bores with outlet openings arranged above the valve stem surface areas to be lubricated and a pin-like restrictor with at least one longitudinal groove is disposed in each bore for controlling the oil flow through the bore and guiding it along the pin-like restrictor which ends above surface area to be lubricated.

Valve timing gear for an internal combustion engine

In an arrangement for supplying cooling oil to the piston of an internal combustion engine which has intake and exhaust valve drive and also fuel injection pump drive components, a pipe is mounted on the engine housing in communication with a cooling oil supply passage and has a free end extending under the piston for spraying cooling oil to the underside of the piston, at least one additional discharge opening is provided on the pipe which is directed toward the intake and exhaust valve drive components and the fuel injection pump drive components.
