摘要： A connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator, with at least two shell-shaped wedge-shaped pieces, surrounding the shaft end and braced on the final control element, whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces, wherein on the radially inner circumferential surface of the wedge-shaped pieces and on the radially outer circumferential surface of the shaft end of the gas exchange valve, protrusions and recesses that mesh with one another are provided. To enable rotary motions of the shaft end relative to the wedge-shaped pieces, the latter adjoin one another without gaps in the circumferential direction, forming an encompassing wedge-shaped sleeve, whose inside diameter is slightly larger than the outside diameter of the shaft end of the gas exchange valve, and that the protrusions and recesses mesh with one another with slight play.

IPC分类号： F01L9/02
摘要： A device for controlling gas-exchange valves of an internal combustion engine is provided, which device has hydraulic valve actuators each allocated to one gas-exchange valve. Each valve actuator has an actuating piston acting on the gas-exchange valve, and two hydraulic working chambers delimited by the actuating piston, of which the first working chamber acting upon the gas-exchange valve in the closing direction is constantly filled with fluid under pressure, and the second working chamber acting upon the gas-exchange valve in the opening direction is able to be alternately filled with fluid under pressure and relieved via two electric control valves. For the purpose of cost reduction, provided for each valve-actuator pair is a single first electric control valve that is acted upon with the fluid pressure on the intake side, and is connected on the outlet side to the second working chamber of one valve actuator. The second working chamber of the other valve actuator is filled with fluid with the aid of a switchover valve and the fluid pressure in the second working chamber of the one valve actuator.

摘要： An apparatus for controlling gas exchange valves includes at least one valve positioner, associated with a gas exchange valve, and a pressure supply device which supplies the valve positioner with a fluid under high pressure. The valve positioner encompasses a working cylinder having a positioning piston, coupled to the gas exchange valve, which delimits an upper pressure space for opening the valve and a lower pressure space for closing the valve, and encompasses a control valve controlling the hydraulic pressure in the pressure spaces. In order to reduce the manufacturing costs and electrical energy demand of the apparatus, the upper pressure space is connected directly, and the lower pressure space via a restrictor throttle, to the pressure supply device; and the control valve is connected to the lower pressure space and to a relief line. Depending on the switch position, the control valve additionally connects the lower pressure space to the relief line or blocks it off from the relief line.

摘要： The valve brake (50) incorporates a damping system (31) with throttles (35,35') for the oil which may be forced out via a leakage channel (46). There is an axial bore (37) with a stop valve (38) connected to radial bores (36). The piston (18) of the damper also acts as an actuator piston and oil is introduced through wide radial bores (201,202) in communication with control valves and a high-pressure oil supply.

摘要： The invention relates to an electrohydraulic valve control system (10) of an internal combustion engine, comprising at least one actuator (24) which acts on a gas exchange valve (38). Said actuator, in turn, comprises at least one working chamber (30) which is connected to a high-pressure hydraulic accumulator (16) for actuating the actuator (24) in such a way that it moves from a first position to a second position, and which is separated from a low-pressure return line (56). In order to actuate the actuator (24) in such a way that it moves back from the second position into the first position, the working chamber (30) is connected to the low-pressure return line (56) and is separated from the high-pressure hydraulic accumulator (16). In order to easily maintain the pressure constant or to cause a pressure drop in the high-pressure hydraulic accumulator (16), the working chamber (30) is simultaneously connected to the high-pressure hydraulic accumulator (16) and to the low-pressure return line (56).

摘要： An electrohydraulic valve control (10) of an internal combustion engine includes at least one actuator (24) that acts on a gas exchange valve (38). This actuator (24) in turn has at least one working chamber (30), which in order to switch the actuator (24) from a first position into a second position, is connected to a high-pressure hydraulic accumulator (16) and shut off from a low-pressure return (56). In order to switch the actuator (24) from the second position back into the first position, the working chamber (30) is connected to the low-pressure return (56) and shut off from the high-pressure hydraulic accumulator (16). The pressure in the high-pressure hydraulic accumulator (16) is kept constant or reduced in a simple manner by virtue of the working chamber (30) being connected to the high-pressure hydraulic accumulator (16) and the low-pressure return (56) at the same time.
