摘要： The invention relates to a register charging unit for compressing charge air supplied to an internal combustion engine, having a first register stage comprising a first compressor, having a second register stage comprising a second compressor, wherein charge air can be applied to the first compressor and the second compressor in parallel via a charge air line, having a bypass line that creates an air-conveying connection between a downstream branch point behind the first compressor to an upstream supply point in front of the second compressor, wherein a compressor sequence valve is disposed in the region of the supply point in the charge air line for opening and closing both the charge air line and the bypass line. The invention further relates to a compressor sequence valve having a housing, comprising a first inlet region, a second inlet region, and an outlet region that is connected to the first inlet region and the second inlet region in a flow-conducting manner, wherein a first sealing element for opening and/or closing of the first inlet region is operatively connected to a second sealing element for opening and/or closing the second inlet region such that an opening of the first sealing element brings about a seal by the second sealing element, for use in a register charging unit.

摘要： The invention relates to a connection (18) between a stem end (14) of a gas exchange valve (1) in an internal combustion engine and an actuator body (2) of a valve actuator (4), with at least two shell-like collets (22, 24), surrounding the stem end (14), supported on the actuator body (2), the radial outer surfaces of which have a conical shape and which are surrounded by at least one conical taper sleeve (26), the radial inner surface of which has a conical shape complementary to that of the conical shape of the collets (22, 24). On the radial inner surface (38) of the collets (22, 24) and on the radial outer surface (40) of the stem end (14) of the gas exchange valve (1), interlocking projections (42) and recesses (44) are provided. According to the invention, in order to permit a rotation of the stem end (14) relative tot the collets (22, 24), said collets connect together with no gap to give a continuously encompassing collet (22, 24), the internal diameter of which is slightly greater than the external diameter of the stem end (14) of the gas exchange valve and the projections (42) and recesses engage with a slight play.

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 ignition device (11) for a multicylinder internal combustion engine must be designed so that it is operationally reliable under shaking accelerations of the internal combustion engine. The ignition device (11) has rod-shaped ignition coils (12) corresponding to the number of cyclinders of the internal combustion engine. An end section (22) of each ignition coil (12) is formed by a part of a core (23) of the ignition coil (12) projecting from a housings (20) of the ignition coil (12). A buffer is arranged on this. The other end section (21) of the ignition coil (12) is formed by a high voltage dome (27) which is contained in a socket (39) of elastic material supported in the spark plug bore (15) of a cylinder head (13) of the internal combustion engine. The ignition device (11) is maintained elastically tensioned at the two end sections (21, 22) in the cylinder head (13) of the internal combustion engine by a retaining element (33). The high voltage transmission to an associated ignition coil (16) is effected in a flexible manner through a high voltage contact element (48) which is designed as a spring.

摘要： A gas valve, in particular a metering valve for a gaseous medium, having a valve washer (10) which is arranged in the gas valve so as to be able to move with respect to a longitudinal axis (8), and having a valve plate (12) with a valve seat (19) formed thereon, wherein the valve washer (10) interacts with the valve seat (19) for opening and closing the gas valve, and having a first circumferential sealing edge (30) between the valve seat (19) and the valve washer (10). The valve washer (10) has a central opening (13) through which the gaseous medium passes, wherein the first circumferential sealing edge (30) surrounds the central opening (13) and wherein, in the central opening (13), there is formed a first pressure face (25) upon which the gaseous medium acts in the closing direction. Furthermore, there is arranged on the valve washer (10) a second pressure face (26) which is formed radially outside the first circumferential sealing edge (30) and on which the gaseous medium also acts. The first pressure face (25) and the second pressure face (26) are connected via a connection passage (15; 17; 24) formed in the valve plate (12).

摘要： The invention relates to a device for controlling a cross-section of an opening in the combustion cylinder of an internal combustion engine, said device comprising a gas exchange valve which is integrated into the combustion cylinder and an actuator (16) which drives the valve element (15) in a closing and opening movement. In order to reduce the impact speed of the valve closing body of the valve element on the valve seat during the closing movement of the valve element, a valve brake (50) acts during the final closing course of the valve element. Said valve brake comprises a hydraulic damping element (31) having a fluid displacement volume which flows over a cross-section of a throttling orifice (35), and a control unit (49) for controlling said cross-section according to the viscosity of the displacement volume.

摘要： The invention relates to a device for repositioning a rotating element in a defined base position. Said device comprises a spatially fixed cam (13) and a driving cam (14) which is coupled to the rotating element and can be moved in front of the fixed cam (13), each cam comprising a stop face (131, 132, 142) on opposite sides. The inventive device also comprises a clip spring (18) which clips the cams (13, 14) in a prestressed manner with two bent spring legs (181, 182). In order to ensure that there is no rotational play between the clip spring (18) and the cams (13, 14) in the base position, in at least one section of the spring leg (181) extending over the stop faces (141) of the cam, an elastic spring element (19) is provided, said spring element supporting the associated stop face (141) with a spring force which is smaller than the prestress force of the clip spring (18).
