    Abstract: A piston assembly for a fuel pump comprises a first piston sub-assembly and a second piston sub-assembly. The first piston sub-assembly comprises a first piston portion, a first check ball connected to a first spring and a first O-ring. The first check ball forms a fluid tight seal against the first piston portion when the first spring is uncompressed. The first check ball allows fluid flow relative to the first piston portion when the first spring is compressed. The first O-ring has a front side and a back side. The first O-ring forms a fluid tight seal relative to the first piston portion. The second piston sub-assembly comprises a second piston portion, a second check ball connected to a second spring, and a second O-ring. The second check ball forms a fluid tight seal against the second piston portion when the second spring is uncompressed. The second check ball allows fluid flow relative to the second piston portion when the second spring is compressed. The second O-ring has a front side and a back side. The second O-ring forms a fluid tight seal relative to the second piston portion. The fluid flow relative to the first piston portion allows fluid to contact the front side of the second O-ring and the back side of the first O-ring.

    Abstract: The invention relates to a two-piece piston (1) for an internal combustion engine, comprising a piston upper piece (2) and a piston lower piece (2). A cylindrical molding (24) is arranged on the underside of the piston upper piece (2), facing away from the piston crown, lying coaxial to the piston axis (15), with two radial outward-facing hooked projections (27) on the end thereof facing away from the piston crown. The piston lower piece (6) has an opening (16) on the piston crown side, in which the cylindrical molding (24) with the projections (27) is introduced and rotated on assembly of the piston upper piece (2) on the piston lower piece (6), such that the projections (27) engage behind the edge of the opening (16).

    Abstract: An actuator is equipped with a cylinder body in the interior of which a piston is disposed for displacement therein. A piston rod connected to the piston projects outwardly to the exterior from an end of the cylinder body. A guide unit, having a guide body that is attached to the cylinder body, and a pair of guide rods, which are disposed displaceably with respect to the guide body, are disposed detachably on the cylinder body. Additionally, by mutually interconnecting the guide rods of the guide unit and the piston rod through a connecting plate, when the piston rod is displaced in an axial direction, the piston rod is guided by the pair of guide rods.

    Abstract: A piston and method is provided that inhibits the potential catastrophic damage to an internal combustion engine, thereby reducing the risk of costly damage to the engine. The piston includes a piston body having an upper combustion surface separated from an internal cooling chamber by a wall. The a pocket extends into the upper combustion surface to a closed bottom surface of the wall. A tubular member is disposed in the pocket. The tubular member extends upwardly from the upper surface. Should a valve head drop from its normal operating position, the valve head impacts the tubular member and forms a blow-by through passage extending from the upper combustion surface into the cooling chamber.

    Abstract: The invention relates to a piston for a piston-cylinder arrangement, particularly a shock absorber piston, which includes a piston body, that has a circumferential surface. A sealing collar has an outer circumferential surface, an inner circumferential surface, a first peripheral surface, and a first sealing lip, and extends around the circumferential surface of the piston body and covers at least part of the circumferential surface in the axial direction. The first peripheral surface connects the two circumferential surfaces to each other at a first end of the sealing collar. The first sealing lip is delimited by the first peripheral surface and the outer circumferential surface, and the first sealing lip is configured evenly in the circumferential direction.
