Definitions
- the invention relates to a Gas monocytes merit- direction according to claim 1.
- a generic gas exchange valve actuating device for transmitting a drive movement to a gas exchange valve and with an internal combustion engine brake unit which comprises a hydraulic actuator.
- the internal combustion engine braking unit on a pressure relief valve.
- the energy storage unit is formed by a hydraulic pressure accumulator unit, whereby it can be realized structurally simple, in particular if the actuator means is formed by a hydraulically actuated Aktuatorkolben and / or the locking unit is hydraulically formed.
- a hydraulic pressure storage unit should be understood as meaning, in particular, a storage unit in which hydraulic pressure fluid can be stored, in particular under pressure. Does the energy storage unit at least one mechanical
- FIG. 1 shows individual parts of a Gas batventilbetuschists- device of an internal combustion engine, which is intended to transmit a drive movement to gas exchange valves 10a, with only one gas exchange valve 10a is indicated.
- the gas exchange valve operating device comprises a camshaft 19a having an exhaust cam 20a and a brake cam 21a of an engine brake unit IIa.
- the exhaust cam 20a acts on a first end of a Auslrawkipphebels 22a, which is pivotally mounted on a rocker shaft 23a and acts with its second end to the provided as an outlet valve gas exchange valve 10a.
- the pressure limiting valve 16a is closed during the extension of the actuator means 12a without or without significant counterforce and opens when the actuator 12a at a pressure slightly above a maximum system pressure in the inlet channel 27a of the engine or, if the rocker arms 22a, 24a during the extension of the actuator means 12a are coupled. In principle, however, it is also conceivable that a bypass without corresponding pressure relief valve 16a is provided.
