摘要： A piston rod and a piston are installed with freedom of axial movement in a cylinder filled with a working medium, the piston dividing the working space into a space on the piston-rod side of the piston and a space on the side of the piston facing away from the piston rod. A stop disk is mounted on the piston rod in addition to the piston rests against a retainer provided on the cylinder to limit the outward movement of the piston rod during a fire.

摘要： Piston ring including a covering surface which covers a circumferential surface of a piston, and supporting segments having retaining surfaces which engage the upper and lower sides of the piston. The piston ring has a butt joint which enables the piston ring to be elastically deformable radially, the butt joint being designed at one end of the covering surface with at least one tongue which engages in a cutout in the other end of the covering surface. The tongue is designed with at least one retaining segment which runs in the circumferential direction and engages in a supporting manner in each case on the upper and lower side of the piston.

摘要： Piston-cylinder unit comprising a cylinder in which a work space is filled with a work medium and which is limited by a closure and is sealed by at least one seal. The closure is fixed axially by a positive engagement with the cylinder up to a temperature threshold and the closure can carry out an axial movement for relieving pressure above the temperature threshold. A cutting device cancels the sealing function of the seal during the axial movement of the closure for relieving pressure.

摘要： A piston ring includes a lateral surface which covers a circumferential surface of a piston and support segments with retaining surfaces which engage with the top and bottom of the piston. A piston ring joint allows the piston ring to be elastically deformed in the radial direction and is provided with a tongue at one end of the lateral surface, which tongue engages in an opening in the other end of the lateral surface. The tongue is designed with retaining segments which extend in the circumferential direction and continue as extensions of the support segments. The retaining segments engage supportively with the top and bottom of the piston. The opening is provided with carrier segments at least in certain areas of the circumference of the piston ring extensions of the support segments and holding the ends of the piston ring in place axially with respect to the piston, the carrier segments being supported in the axial direction of the piston on the retaining segments. The piston ring joint of the piston ring has at least one sealing surface between the ends of the piston ring.

摘要： A method for manufacturing a piston, wherein the piston includes a piston body with through-channels for fluid which are covered by valve disks on supporting bodies with valve support surfaces. The piston body is constructed in one piece in a disk-shaped manner by press stamping. Starting from a base body of the piston, the raised areas of the piston body on one side of the piston are formed as depressions on the axially opposite side. The piston has at least one support for the valve disks whose axial height is adapted to the height of the support surfaces. The support on both sides of the piston is stamped from the base body of the piston and the valve support surfaces and the support are machined in the same manufacturing step on a common plane.

摘要： A sheet-metal piston rod guide for a piston-cylinder unit in which a piston rod is axially movable, includes a slide bush which is centered by a guide sleeve which adjoins a closure ring which delimits the working chamber and in turn merges into an axial casing. The axial casing centers the entire piston rod guide. A piston rod seal surrounds the piston rod and seals the working chamber. The guide sleeve is supported in the axial and radial directions against a bearing ring which bears the piston rod seal and extends in the radial direction. The bearing ring has a radial support surface with respect to the casing so that the casing, the closure ring, the guide sleeve, and the bearing ring form a force bearing arrangement which is closed with regard to the bearing of forces.

摘要： Switching valve with a valve body, which separates two working spaces filled with a fluid. The valve body has pass-through openings which are covered except for an inlet cross-section, where the inlet cross-section is controlled by a switching disk as a function of the direction of flow in the switching valve. Between the switching disk and the inlet cross-section, at least one spacer disk is provided, which has at least one opening, which communicates with the inlet cross-section, where the opening has a larger two-dimensional area than the inlet cross-section.
