Abstract: A dashpot featuring amplitude-dependent shock absorption, especially intended for the wheel of a vehicle and including a hydraulically parallel cylindrical pressure-compensation chamber (8). The pressure-compensation chamber is partitioned by an axially displaceable floating piston (10). At least one face (25) of the floating piston is provided with a resilient bumper (18). The object is a dashpot with a floating piston that arrives more gently at its limit inside the pressure-compensation chamber (8). The bumper is accordingly accommodated in an axial hollow (17) that extends through the body (15) of the floating piston.

Abstract: A hydraulic dashpot for motor vehicles, with a cylinder and a primary piston. The cylinder (1) is charged with shock-absorption fluid. The primary piston (2) is mounted on the lower end of a piston rod (8) and partitions the cylinder into two chambers (3 & 4). The piston rod travels axially into and out of the cylinder. The primary piston is provided with breaches, with shock absorption valves (5) that can vary the cross-section of the breaches, and with a bypass system comprising at least two mutually dependently controlled bypasses between the two compartments. The object of the present invention is to improve a hydraulic dashpot of the aforesaid genus to the extent that the at least two bypass channels, although they can be opened and closed mutually dependently, need not be opened and closed sequentially.

Abstract: A shock-absorbing piston for hydraulic fixtures, especially hydraulic dashpots for motor vehicles, and separating two hydraulics chambers. The body of the piston is breached by one or more ports. The end of each is blocked by a resilient or resiliently loaded cap. The object is to improve the flow of hydraulic fluid. The ports (13 & 14) are sickle-shaped and the cap rests eccentric against the face of the piston's body (16).

Abstract: An assembly for sealing and centering a piston rod (3) at its point of penetration in a two-cylinder dashpot or two-cylinder telescoping leg. The assembly seals and centers it as the piston rod travels into and out of the dashpot. The assembly is provided with at least one seal (13) outside the dashpot, toward the inside with at least one piston-rod sealing ring (7), and with at least one channel between them. The channel extends into a gas accommodating space (19) left between the dashpot's outer cylinder (1) and its inner cylinder (2). The gas channel is provided with a checkvalve. One object is components that eliminate the need for a high-pressure sealing ring in contact with the piston rod. Another object is a simpler checkvalve in the overflow channel. The gas channel upstream of the gas-accommodating space is provided with a flow-controlling diaphragm (22).

Abstract: A regulable hydraulic dashpot for motor vehicles and including a cylinder (1) filled with hydraulic fluid and a piston (2) that is attached to the end of a piston rod (7), travels back and forth inside the cylinder, and divides it into two chambers (3 & 4) that communicate through at least one bypass. The bypass's cross-section can be varied in size by a component that is, preferably continuously, controlled by a motor or magnet. To facilitate adjusting the dashpot, the cross-section varying component is a plate-shaped slide (23) provided with one or more breaches (25) and traveling from side to side, preferably in a slot (24), with its flat surface (27) subjected to fluid from each cylinder chamber alternately by way of channels (14, 15, & 16).
