摘要： Diaphragm compressors having an electric motor (10) with a drive shaft (18), movement transmission means (32, 42, 50, 52) which can be set in motion by way of the drive shaft (18) and via which a rotational movement of the drive shaft (18) can be converted, a piston rod (58) which is coupled to an output member (40) of the movement transmission means (32, 42, 50, 52) and to a diaphragm (72, 74), a compressor chamber (80, 82) which is delimited by way of the diaphragm (72, 74) and a compressor head (76, 78), and the volume of which can be varied by way of the movement of the diaphragm (72, 74), are known. In order to avoid damaging tumbling work of the diaphragm, it is proposed according to the invention that the movement transmission means (32, 42, 50, 52) are formed by way of an epicyclic gear mechanism (44), the output member (40) of which is configured as a crank (42), the input shaft (48) of which is guided eccentrically with respect to the rotational axis of the drive shaft (18), and the output shaft (38) of which has an axial offset (A) with respect to the input shaft (48), which axial offset (A) corresponds to an eccentricity (E) of the input shaft (48) with respect to the rotational axis of the drive shaft (18).

摘要： The invention relates to control devices for internal combustion engines comprising a flow housing (10), in which a flow-through channel (12) is formed, and which has a first channel section (32) with a first flow cross-section, a second channel section (34) in which the flow cross-section is reduced and a third channel section (36) downstream of the second channel section (34), in which the channel (12) continues with reduced flow cross-section, a valve body (18) that is rotatably arranged on a shaft (16), an actuator (24) and a first pressure measurement point (42) in the first channel section (32) of the flow housing (10) and a second pressure measurement point (44) in the third channel section (36). According to the invention, in order to increase the measuring accuracy of a mass flow, even for small released flow cross-sections, the second pressure measurement point (44) in the third channel section (36) is arranged within an axial section (50) through which the valve body (18) moves during its rotation, on the region of the flow housing (10) at a distance from the shaft (16) when viewed in the peripheral direction of the housing wall (14).

摘要： Regulating devices for internal combustion engines are known, having an intake pipe (12), an exhaust gas recirculation pipe (16) that opens into the intake pipe (12), a housing (10) in which the intake pipe (12) and the exhaust gas recirculation pipe (16) are formed and a shaft (28) acting as an axis of rotation (30) on which a regulating element (36) is eccentrically mounted, the shaft being arranged perpendicularly to the centre line of the intake pipe (12) and of the exhaust gas recirculation pipe (16), wherein in a first end position, in which the intake pipe (16) is at least choked upstream of an opening in the exhaust gas recirculation pipe (16), a normal vector of a first surface (44) of the regulating element (36) points to the upstream portion of the intake pipe (12), and in a second end position, in which the exhaust gas recirculation pipe (16) is closed, a normal vector of a second surface (48) of the regulating element (36) points to the exhaust gas recirculation pipe (16). However, these devices have the inconvenient that increased flow resistances caused by choking the pipes also reduce the performance of a downstream compressor and of the internal combustion engine. In order to solve this problem, the invention proposes the formation of guide ribs (52) on the first surface (44).

摘要： Regulating devices for internal combustion engines are known, having an intake pipe (12), an exhaust gas recirculation pipe (16) that opens into the intake pipe (12), a housing (10) in which the intake pipe (12) and the exhaust gas recirculation pipe (16) are formed and a shaft (28) acting as an axis of rotation (30) on which a regulating element (36) is eccentrically mounted, the shaft being arranged perpendicularly to the centre line of the intake pipe (12) and of the exhaust gas recirculation pipe (16), wherein in a first end position, in which the intake pipe (16) is at least choked upstream of an opening in the exhaust gas recirculation pipe (16), a normal vector of a first surface (44) of the regulating element (36) points to the upstream portion of the intake pipe (12), and in a second end position, in which the exhaust gas recirculation pipe (16) is closed, a normal vector of a second surface (50) of the regulating element (36) points to the exhaust gas recirculation pipe (16). However, these regulating devices have the inconvenient that the introduction of the exhaust gas disturbs the flow and thus leads to increased condensate formation and increased flow resistances. In order to solve this problem, the invention proposes the formation of guide ribs (52) on the second surface (50), along which an exhaust gas stream flows into the intake pipe (12) when the exhaust gas recirculation pipe (16) is opened.

摘要： Coolant pumps for internal combustion engines are known, comprising a drive shaft (18), a coolant pump impeller (20) which is securely arranged on the drive shaft (18) at least in a rotationally fixed manner and via which coolant can be conveyed, an adjustable control slider (58) via which a flow cross-section of a ring gap (62) between the outlet (64) of the coolant pump impeller (20) and the surrounding conveying channel (12) can be controlled, a control pump (32) having a control pump impeller (22) which is arranged on the drive shaft (18) at least in a rotationally fixed manner, a flow channel (24) of the control pump (32) in which a pressure can be generated by rotating the control pump impeller (22), a pressure channel (92) via which an outlet (30) of the flow channel (24) can be fluidically connected to a first pressure chamber (80) of the control slider (58), which is formed on the axial side of the control slider (58) facing away from the coolant pump impeller (20), and a valve (84) via which a flow cross-section (90) of the pressure channel (92) can be closed and released. According to the invention, in order to be able to guarantee an emergency operation with maximum coolant supply of the coolant circuit, without the use of a return spring, the flow channel (24) is fluidically connected to a second pressure chamber (82) of the control slider (58) via a connection channel (94), which is formed on the axial side of the control slider (58) directed towards the coolant pump impeller (20).
