摘要： An oil ring assembly for internal combustion engine pistons including an annular split piston ring with an inner circumferential groove, a radially expandable split annular spring in the groove, and a bridging means in the groove spanning the gap between opposite ends of the piston ring. The spring is preferably a coil spring and the bridging means is preferably a cylindrical arcuate segment located between opposite ends of the spring with pins on each end extending inside the coils of the spring. Alternatively, the arcuate segment may be formed from a tightly wound coil spring. A second enbodiment utilizes a serpentine expander as the spring and the bridging means comprises a flat arcuate segment located in a notch in the expander adjacent the gap in the piston ring.

摘要： A pump body includes a pump inserted portion inserted in a pump mount hole. A cylinder has a compression chamber at one end side and opens in an end surface of the pump inserted portion at the other end side. A plunger is actuated by a cam and is movable in the cylinder. A seal member restricts fuel in the compression chamber to leak through a slidable gap between the plunger and the cylinder and restricts lubricating oil flowing through the slidable gap into the compression chamber. A retaining member retains the seal member at a predetermined position in the axial direction and restricts the plunger from falling out of the cylinder. The retaining member is press-fitted to an end of the pump inserted portion.

摘要： A combined oil ring 1 is comprised of an oil ring 2 with a generally I-shaped cross section including upper and lower rails 6, 7 joined by a web 8 for sliding on an inner circumferential surface 10 of a cylinder 9, and a coil expander 3 to press the oil ring 2 radially outwards. The combined oil ring 1 contains a seal member 14 for sealing a gap of the oil ring 2 and capable of making contact with the upper rail 6 in an outer circumferential groove 12 formed by the web 8 and the upper and lower rails 6, 7. The seal member 14 may include a structure where the edge of the seal member 14 is bent, and catches in a window hole 13 formed on the web 8 of the oil ring 2.

摘要： The present disclosure provides a sealing ring assembly having ring segments configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. The sing segments are configured to move radially outward and wear during operation of the piston via the cylinder device. The ring segments include, for example, wedge-shaped features that engage with corresponding wedge recesses in the interfaces between ring segments. The sealing ring assembly may include a high-pressure boundary and a low-pressure boundary. As the sealing ring wears, the ring segments stay engaged with the interfaces, so that ring gaps do not form on the low pressure boundary.

摘要： A piston is described for the compression of a pneumatic fluid in a compression chamber of a cylinder comprising:

a cylindrically shaped piston body, adapted to be arranged slidably within said cylinder, and having a side wall and a top wall; along a circumferential perimeter of said side wall of the piston body a seat being defined; and
a sealing assembly accommodated in said seat, and adapted to ensure the fluid-tightness along said circumferential perimeter;
the sealing assembly comprising a plurality of sealing elements, having shapes complementary to one another, and configured so that the wear of a sealing element along said circumferential perimeter corresponds to a sliding in the radially outer direction of the adjacent sealing element.

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.
