摘要： A working cylinder which has end-position damping. A piston ring passes over an axially offset pressure medium connection and encloses a pressure medium damping volume. The piston ring includes a ring joint which has a base section and a projection section. The piston ring is of sealing construction. The pressure medium flows out of the pressure medium damping volume via an axial transfer channel, which can be defined by an axial cylinder-tube groove or an axial piston-ring groove. Also, there is a damping piston ring, which is of sealing construction and which has an axial piston-ring groove.

摘要： The piston ring unit includes a plurality of piston rings and an inner contact ring. A plurality of piston rings are disposed adjacent to each other in an axial direction of the piston such that joints of plurality of the piston rings do not overlap with each other in the axial direction. An inner contact ring is interposed between an outer circumferential surface of the piston and an inner circumferential surface of the piston ring in a state where the inner contact ring extends over all of the plurality of piston rings in the axial direction, and is disposed such that an opening of the inner contact ring does not overlap with the joint of the at least one piston ring as viewed in a radial direction of the piston.

摘要： A piston for an internal combustion engine may include a piston head, an encircling fire land, and at least one annular groove structured to receive a piston ring and disposed contiguous to the fire land. The piston may include a first fire land portion having a first axial height h1, a second fire land portion having a second axial height h2, and a third fire land portion having a third axial height h3. The first fire land portion may have an upper external diameter D1. The third fire land portion may have a lower external diameter D3. A transition from the first to the second fire land portion may have a first external diameter D12. A transition from the second to the third fire land portion may have a second external diameter D23. The relationship (D12−D23)/h2>(D23−D3)/h3 may apply.

摘要： A piston assembly for a nailer is provided, and includes a piston body with an upper surface, a lower surface and a peripheral edge. A peripheral gland is located between the upper and lower surfaces, the gland having an inner closed end and defining an annular space. An annular piston seal is disposed in the gland, and a plurality of spaced air ports are disposed adjacent the peripheral edge, the ports each being in fluid communication with the gland. The gland and the seal are dimensioned so that during a power cycle of the nailer, pressurized air generated during a fastener driving stroke enters the ports and radially expands the seal for enhancing friction between the seal and a surrounding cylinder. During a return stroke, the seal is radially retracted within the gland to reduce friction between the seal and the cylinder.

摘要： A piston configuration is provided, the configuration including a piston having a ring seat and a piston ring disposed within the ring seat. The piston ring is configured to form a sealing surface between a surface of the piston ring and a surface of the ring seat. The sealing surface is formed when a first pressure on a first side of the piston ring is greater than a second pressure on a second side of the piston ring. At least one fluid channel is configured to increase a surface area on the piston ring that is subject to the second pressure.

摘要： A replacement split boot assembly for a constant velocity joint on a vehicle is provided with slip-fit, non-threaded fasteners. The split boot body has pairs of opposing tabs across a longitudinal slit. Each of the tabs has a hole. The slip-fit, non-threaded fasteners have a head on one end and a radial projection spaced a distance from the head on the shaft. The fasteners are adapted to be urged through the opposing tab holes on the split boot body until the pair of tabs is located between the head of the fastener and the radial projection on the shaft. A retainer is used to lock the tabs between the head of the fastener and the retainer by urging the retainer over the radial projection of the fastener.

摘要： A rubber plug for a water-proof connector has an inner cylinder and an outer cylinder. The rubber plug into which an electrical wire inserted and which is inserted into a cylindrical structure of the water-proof connector sealingly closes the gap between the electrical wire and the cylindrical structure. The inner cylinder is provided at a portion which is positioned near the opening of the cylindrical structure of the water-proof connector, for sealingly closing a gap between the electrical cylinder and the inner cylinder. The outer cylinder has an annular groove, and is provided outside the inner cylinder at the portion in such a manner that the outer cylinder surrounds said inner cylinder through the annular groove for closing a gap between the inner cylindrical surface of the cylindrical structure and the outer cylinder.

摘要： In a dust cover (6) for the brake cylinder (1) of a disc brake with a ring-shaped boot (7), with a fixing torus (8) at a first end of the boot engaging an annular groove (9) in the piston (3) of the brake cylinder (1) and with a stiffening lining in the shape of a ring (11) which is at least partly surrounded by the material of the boot (7) and which urges the second end of the boot (7) against the inside wall (12) of a ring-shaped recess (5) in the front side (4) of the brake cylinder (1) said second end of the boot (7) forms a unilaterally open, ring-shaped bag into which said ring (11) is inserted. Within said bag the ring (11) is formed with perforations (14) which are penetrated by the material of the boot (7). A radial collar (13) of the ring (11) which projects out of said bag constitutes a surface of abutment for an assembly tool.

摘要： For carrying out lubrication between a piston (17) and a piston ring (21) installed in an annular groove (23) of the piston, the piston ring comprises a recessed portion (15a, 15b) which is partially recessed from an upper axial end (27) of the piston ring. Lubricating oil is mixed with blow-by gas and flows into the annular groove through the recessed portion. As a result, the lubricating oil is effectively supplied to the annular groove. Therefore, the lubrication is favorably carried out between the piston ring and the piston. The piston ring may be formed from a piston ring member (10) of a ring-shaped plate which has the recessed portion on an outer peripheral surface (13) thereof.
