摘要： A fluid cylinder comprises a cylinder tube having a first tube end and a second tube end with respect to a tube axis of the cylinder tube, wherein the tube axis refers to the axis of the cylinder tube and the extension of the axis; an opening arranged at the first tube end for allowing fluid to enter into the cylinder tube; a piston; a sealing member arranged on the piston and adapted to provide a fluid-tight sealing between the piston and an inner wall of the cylinder tube; and a driving member adapted to drive the piston to perform a piston motion in the cylinder tube along the tube axis, wherein the cylinder tube, the opening, the piston, the sealing member, the inner wall and the driving member are adapted.

摘要： A piston assembly may include a piston rod and a piston disposed on the piston rod. The piston may include a frame end cap defining a through-bore for receiving the piston rod, and the frame end cap may form a first end of the piston. The piston may include an outer end cap defining a through-bore for receiving the piston rod, and the outer end cap may form a second end of the piston. The piston may also include a center support defining a through-bore for receiving the piston rod. The center support may be disposed between the frame end cap and the outer end cap, and an outer surface of the piston rod and an inner circumferential surface of the center support may define a radial gap.

摘要： An internal combustion engine may include an engine block, a cylinder within the engine block, and a piston within the cylinder. The piston may have an outer peripheral wall, and a groove in the outer peripheral wall of the piston may have a first edge and a second edge spaced from the first edge. The piston may have a piston ring in the groove, and the piston ring may have a shape that meanders within the groove, such that the shape of the piston ring differs from a shape of the groove and such that the piston ring does not substantially fill the groove. The piston ring may be constructed of a material that when subjected to heat causes a shape of the meanderings to change, thereby enabling the piston ring to expand in an axial direction of the piston, between the edges of the groove.

摘要： A linear reciprocating engine may include an engine block, a cylinder having combustion chambers at opposing ends, cylinder heads located at an end of the respective combustion chambers, respectively, and a double-faced piston. The engine may further include piston rod portions extending from both faces of the piston through the combustion chambers. The engine may further include an exhaust outlet in a peripheral cylinder wall and elongated channels in the piston rod portions being configured to serve as an intake inlet for gas from a location external to the cylinder. When the piston is in a combustion stage in a first combustion chamber, the piston blocks the exhaust outlet from communicating with the first chamber with the first channel access opening outside the first chamber, while simultaneously the exhaust outlet is in communication with a second combustion chamber with the second channel access opening within the second chamber.

摘要： A separating device for fluid media receivable in a working housing (1). A separating piston (3) is inside the working housing (1) and separates two media compartments (5, 7) from one another in a media-tight manner. The separating piston (3) is provided along its external circumference with a guide (19). During a transversing movement of the separating piston (3) inside the working housing (1), the guide bears slidably on the housing inner wall (21) and is an integral component of the separating piston (3).

摘要： The invention relates to a die casting ring (1) internally fitted with radial teeth (11) to be engaged into matching seats (22) provided on a piston (2). This piston-ring assembly prevents mutual rotation or axial translation, in addition to ensuring an optimal seal against infiltration of liquid metal during the die casting process. When the ring has a cutout (10), it can be mounted accurately onto the piston because the teeth (11) allow the cutout to be positioned anywhere relative to the piston.
