A rotary pump including: a pump housing including a circumferential wall, which surrounds a delivery chamber, a first end-face wall and a second end-face wall which delineate the delivery chamber at its end-face sides; a rotor, which can be rotated in the delivery chamber, for forming delivery cells; a pressure outlet which emerges on an outer end-face side of the first end-face wall facing away from the delivery chamber; an outlet gasket which is provided on the outer end-face side of the first end-face wall, for sealing off the pressure outlet; and a pressing device for charging the outlet gasket with an axial pressing force.

A pump for applying fluid to an assembly, the pump including: a pump housing featuring a circumferential wall surrounding a delivery chamber of the pump, an end-facing housing wall including an outer end-facing surface of the housing which faces axially away from the delivery chamber, an inlet and an outlet for the fluid which emerges on the outer end-facing surface of the housing; a delivery member, moveable within the delivery chamber, for delivering the fluid from a low-pressure side of the pump which includes the inlet to a high-pressure side of the pump which includes the outlet; and an axial gasket which fully surrounds the outlet, in order to separate it from the low-pressure side, in an axial view onto the end-facing wall of the housing. The axial gasket is a spring gasket in the form of a disc spring or hollow-profile spring or V-profile spring or bellows spring.

A marine engine has a powerhead having an cylinder block, a cylinder head, and a crankcase; a supercharger providing charge air for combustion in the powerhead, wherein the supercharger discharges the charge air to an outlet duct; and a charge air cooler cooling the charge air prior to combustion in the powerhead. The charge air cooler has an upstream inlet receiving the charge air from the outlet duct and a downstream outlet discharging the charge air to the cylinder head. The downstream outlet is coupled to the cylinder head by a first one of a rigid seal device and a flexible seal device and the upstream inlet is coupled to the outlet duct by a different, second one of the rigid seal device and flexible joint device.

A vane pump comprises a housing and a control slide. A rotor rotates to draw lubricant into a rotor receiving space of the slide via a housing inlet and discharges the lubricant via an outlet. The control slide moves to change its eccentricity relative to the rotor for increasing and decreasing a pressure differential between the inlet and outlet. The control slide is biased in a displacement increasing direction. The control slide has one or more seals defining a control chamber with housing. The one or more seals includes a seal assembly received in a recess on a control slide outer surface. The seal assembly has a base element in the recess and a bearing element pivotally attached to the base element and bearing against an inner surface of the housing for sealing. The pivotal attachment includes male and female pivotal connectors coupled together.

A seal member includes pushing projections that project from a seal body toward at a groove inner-side circumferential surface and are arranged at intervals in a circumferential direction of the seal body. The pushing projections push the seal body against the groove inner-side circumferential surface and a groove outer-side circumferential surface between the groove inner-side circumferential surface and the groove outer-side circumferential surface. This reduces the gap between the groove outer-side circumferential surface and the seal member in the seal accommodating groove. Thus, salt water is unlikely to collect in the gap between the groove outer-side circumferential surface of the seal accommodating groove and the seal member. This improves the corrosion resistance of the housing and the seal member.

An insert component for a scroll compressor comprises a polymer and at least one reinforcing or lubricating particle. The insert component comprises an annular body and an axial projection. The annular body defines a first centrally-disposed opening having has a central axis extending therethrough. The annular body has a first side comprising a first contact surface configured to engage a partition plate and a second side a second contact surface configured to engage a floating seal assembly. The first contact surface defines a slope between first and second radial locations. The axial projection extends from the annular body and can be received in a second centrally-disposed opening of the partition plate. The insert component can fluidly seal both a first interface between the first contact surface and the partition plate and a second interface between the second contact surface and a floating seal assembly during operation of the scroll compressor.

A pump, wherein a first pressure space and a second pressure space are formed between an end-facing wall of an accommodating housing and a second housing part of a pump insert, wherein an annular sealing element which is arranged between the end-facing wall and the second housing part encloses the second pressure space and seals it off in relation to the first pressure space, wherein the first pressure space is connected via a first outlet channel to a first delivery chamber which is formed between a rotor and a stroke ring of the pump insert, and the second pressure space is connected via a second outlet channel to a second delivery chamber which is formed between the rotor and the stroke ring.

A scroll compressor is provided, comprising: a compression mechanism comprising a non-orbiting scroll member and an orbiting scroll member, wherein the orbiting scroll member is axially displaceable between an engagement position and a disengagement position; a main bearing housing adapted to support the compression mechanism; a back pressure chamber formed between the orbiting scroll member and the main bearing housing, wherein the back pressure chamber is in communication with at least one of the compression chambers via a communication passage provided in the orbiting scroll member or the non-orbiting scroll member and is adapted to apply a back pressure to the orbiting scroll member to bias the orbiting scroll member toward the engagement position; and a first sealing means provided between the back pressure chamber and a suction zone of the compression mechanism and capable of maintaining sealing when the orbiting scroll member is axially displaced.

A rotary pump including: a pump housing including a circumferential wall, which surrounds a delivery chamber, a first end-face wall and a second end-face wall which delineate the delivery chamber at its end-face sides; a rotor, which can be rotated in the delivery chamber, for forming delivery cells; a pressure outlet which emerges on an outer end-face side of the first end-face wall facing away from the delivery chamber; an outlet gasket which is provided on the outer end-face side of the first end-face wall, for sealing off the pressure outlet; and a pressing device for charging the outlet gasket with an axial pressing force.

A rotor assembly for a rotary internal combustion engine is provided. The rotor assembly includes a rotor having a radial groove defined radially in a peripheral surface of the rotor. The groove has a depth and an intermediate shoulder at an intermediate depth. The groove has a first width therealong that is narrower than an intermediate width at the shoulder. An apex seal is received in the groove and protrudes from the peripheral face of the rotor. The apex seal is configured to move radially between a first position and a second position outward of the first position. A biasing member biases the apex seal toward the second position. A platform is disposed in the groove between the apex seal and the biasing member and has a width greater than the first width.
