摘要： A piston ring for a reciprocating compressor is disclosed, including a one-part annular sealing ring with an arcuate outer surface and having a gap between butt ends of the sealing ring. A joint seal seals the gap symmetrical, having two limbs that extend at both sides in the peripheral direction over an angular range of 20° to 180° and having a radially outwardly directed, arcuate limb outer face. The joint seal includes a contact part that extends at both sides in the peripheral direction and projects beyond the limbs in the axial direction. The sealing ring and the joint seal are adapted to each other such that, when assembled, the joint seal rests laterally against the sealing ring via a stop and runs along the gap and covers same in the peripheral direction.

摘要： A reciprocating compressor including an oscillation-type piston mechanism is provided with a piston ring which is mounted in a piston ring groove to seal a space between a piston and a cylinder. A ring groove other than the piston ring groove is provided at an outer periphery of the piston on a side away from the piston ring groove and closer to a crank shaft. A guide ring, which is inhibited from radial movement and shaped like a skirt opened toward the crank shaft, is mounted in the ring groove. Thus, the oscillation-type reciprocating compressor is adapted to maintain long-term durability even under high-pressure compression condition and to prevent heat propagation to a large end portion.

摘要： A fluid control device for use in a high pressure fluid system, the device including a device body with a cavity and a high pressure circuit, a plunger positioned for reciprocal movement in the cavity, and a leakage reduction cap mounted to the plunger for reducing fluid leakage flow. In one implementation, the leakage reduction cap includes a flexible portion positioned between the device body and the plunger, and defining an annular clearance gap between the leakage reduction cap and the device body. The flexible portion of the leakage reduction cap resiliently flexes radially outwardly in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage flow through the annular clearance gap.

摘要： A seal assembly for use with valves is described. An example seal assembly includes a first seal and a second seal opposite the first seal. The first and second seals are to sealingly engage a closure member of a valve and a sealing surface opposite the closure member. A spacer ring is disposed between the first and second seals to prevent the first and second seals from contacting each other. Additionally, the spacer ring is sized so that the spacer ring does not contact the closure member or the sealing surface.

摘要： A piston ring is formed from a ring blank, e.g., a wire, that has a cross sectional profile including upper and lower surfaces that are generally parallel and disposed between inner and outer peripheral faces. The cross sectional profile also includes a hook area at the outer portion of the lower surface that includes a nose area. The nose area is provided with a radius that is as sharp as possible, and is disposed such that a grinding operation performed on the lower surface, e.g., with a single generally planar grinding surface, will also grind the nose area, thereby truncating the nose area and increasing sharpness of the nose area without having to perform additional machining operations.

摘要： A method and device are provided for sealing a first oil environment, which is located on a first side of a movable piston guided in a hollow chamber, from a second oil environment, which is located on a second side of the piston. The piston can move back and forth in the hollow chamber between the two oil environments in the axial direction by a piston stroke length (d). Two annular seal elements are disposed around the movable piston so as to sealingly contact the inner circumferential wall of the hollow chamber. The annular seal elements are spaced from each other by at least a distance (D) in the axial direction that is greater than or equal to the piston stroke length (d).
