摘要： A scroll compressor includes a compressor housing, a high-pressure chamber, a low-pressure chamber, an oil return channel having an oil return throttle arranged therein, a driven eccentric unit, a fixed scroll, an orbiting displacement scroll arranged on the driven eccentric unit which interacts with the fixed scroll, a sliding disk arranged between the orbiting displacement scroll and the compressor housing, a back-pressure chamber arranged adjacent to the orbiting displacement scroll, and a gas connecting channel having a gas connecting throttle arranged therein. The oil return channel fluidically connects the high-pressure chamber with the low-pressure chamber. The gas connecting channel fluidically connects the back-pressure chamber with the high-pressure chamber. The oil return channel and/or the gas connecting channel extends through the sliding disk. The sliding disk includes the oil return throttle and/or the gas connecting throttle.

摘要： A fuel vapor switching and venting valve for an internal combustion engine. The fuel vapor switching and venting valve includes an electromagnet with an armature, a first connection, a second connection, a first valve seat which is arranged between the first connection and the second connection, a spring, a flow limiting element, a second valve seat which is arranged on the flow limiting element, and a valve body coupled to the armature of the electromagnet. The valve body has a first contact surface with which the valve body can be lowered onto and lifted off of the first valve seat, and a second contact surface with which the valve body can be moved against the second valve seat. The second valve seat is axially displaceable. The spring loads the second valve seat in a direction of the valve body.

摘要： A coolant valve for a motor vehicle. The coolant valve includes a housing with an inlet and an outlet, a valve seat which surrounds a flow cross-section formed between the inlet and the outlet, and a control body which is placeable on and liftable off the valve seat via an actuator. The control body has through-going bores via which the inlet is continuously connected to a chamber on a side of the control body which faces away from the inlet, a first annular protrusion which axially extends towards the valve seat and via which the control body is placed on the valve seat, a wall which extends radially between the first annular protrusion and the through-going bores, and an axial groove which extends in a circumferential direction and which is delimited radially to an outside by the first annular protrusion and radially to an inside by the wall.

摘要： An overrun-air recirculation valve includes a flow housing having a flow channel, a valve seat, an actuator, an actuating member movable via the actuator, and a control body fastened to the actuating member. The control body has a lateral outer surface having a bearing edge which is placeable onto and liftable off of the valve seat, a flow-on surface arranged on an axial side facing away from the actuating member, and a wall extending radially inwardly from the lateral outer surface. The flow-on surface has a flow-off edge offset axially to the bearing edge so that a first vector extending radially outwardly from the flow-off edge to a nearest point of the bearing edge to a plane spanned by the bearing edge encloses an angle of

摘要： An integrated semiconductor power transistor package includes a half-bridge electrical circuit with a negative voltage outer terminal of a high-side switch connected in series with a positive voltage outer terminal of a low-side switch, a first and a second substrate, and vertical spacers. The high and the low side switches include semiconductor power transistor dies connected electrically parallel. The first substrate has a cladding layer sinter bonded to one of the semiconductor power transistor dies to define the low-side power switch. The second substrate has a first cladding layer sinter bonded to one of the semiconductor power transistor dies to define the high-side power switch, and a second cladding layer. Vertical spacers sinter bond the semiconductor power transistor die on the first substrate to the second cladding layer. Vertical spacers also sinter bond the semiconductor power transistor die on the second substrate to the cladding layer.

摘要： A valve device for an internal combustion engine. The valve device includes an actuator which moves a valve rod, a housing with an inlet and an outlet, a valve closing member attached to the valve rod which is lowered onto and lifted off of a first valve seat, a non-return plate which is loaded via a spring force in a direction of a second valve seat, and a sealing lip which is formed on the second valve seat or on the non-return plate. The sealing lip extends from the second valve seat in a direction of the non-return plate or from the non-return plate in a direction of the second valve seat. The sealing lip is formed with a free end which is inclined in a direction of a side on which a higher pressure is applied when the non-return plate rests on the second valve seat.

摘要： A divert-air valve for a compressor of an internal combustion engine includes a flow housing with an inlet, an outlet, and a duct arranged therein, an actuator housing, an electromagnetic actuator with an armature arranged in the actuator housing, a control body which is moved by the electromagnetic actuator so as to close off the duct, a housing interior in which the armature moves, openings arranged in the control body, a connector housing arranged to bear axially against the electromagnetic actuator and to at least partially delimit the housing interior, a first sealing ring arranged on the connector housing, and a second sealing ring which bears against the flow housing on an axially opposite side of the connector housing. The openings fluidically connect the housing interior to the duct. The first sealing ring bears against the electromagnetic actuator.

摘要： A side-channel blower for an internal combustion engine includes a flow housing, an impeller which rotates in the flow housing, a housing wall which surrounds the impeller, a drive unit which drives the impeller, impeller blades arranged in a radially outer region of the impeller, a radial gap arranged between the impeller and the housing wall, an inlet, an outlet, two flow channels which connect the inlet to the outlet, and an interruption zone arranged between the outlet and the inlet which interrupts the two flow channels in a peripheral direction. The impeller blades open in a radially outward direction. A respective one of the two flow channels is respectively formed axially opposite to the impeller blades in the flow housing. The impeller blades each comprise a V-shaped cross-section.

摘要： A divert-air valve for a compressor of an internal combustion engine includes a flow housing with a duct, an actuator, a control body moved by the actuator to control a throughflow cross section of the duct, an armature, openings in the control body, a valve housing with a housing wall, a support ring with a ring-shaped plate and a cylinder wall, and a sealing ring which seals the housing interior with respect to a part of the duct. The armature is connected to the control body. The openings fluidically connect the housing interior to a part of the duct. The valve housing surrounds the actuator and a part of the control body. The support ring bears, via the cylinder wall, radially from the outside against the housing wall. The radial sealing ring lies axially against the ring-shaped plate and bears radially at the outside against the housing wall.
