摘要： A hydraulic system for supplying fluid to an actuator comprising a variable speed prime mover drivingly coupled to a variable displacement hydraulic pump. The system is configured to deliver hydraulic fluid via fluid conduits to an actuator. It may deliver hydraulic fluid to an actuator at a first hydraulic pressure at a first rate of pressure rise; and at a second hydraulic pressure at a second rate of pressure rise. The first hydraulic pressure may be greater than the second hydraulic pressure; and the first hydraulic rate of pressure rise may be lower than the second hydraulic rate of pressure rise.

摘要： A hydraulic cylinder includes: a cylindrical cushion bearing that is clamped between a piston and a step portion of a piston rod; a cushion passage that is formed between the cushion bearing and a bearing receiving portion and that imparts resistance to the flow of the working oil passing therethrough; and a check seal that is provided between the inner circumference of the cushion bearing and the outer circumference of the piston rod. The check seal shuts off the flow of the working fluid from a connection gap between the piston rod and the piston towards the rod side chamber through the annular gap and allows the flow of the working fluid from the annular gap towards the bottom-side chamber through the connection gap.

摘要： A pneumatic cylinder having end position damping of the cylinder piston is controlled by means of a vent path and a control valve, the control valve comprises a control piston, the control side of which is pressurized by a pneumatic pressure which exists in a control chamber. The movement of the control piston into its closing position is pneumatically controlled by the increasing pressure in the damping chamber during the beginning of the damping. No additional components or controls are to be provided, so that the control of the end position damping occurs exclusively by the pressure conditions prevailing at the time when the damping begins.

摘要： A hydraulic oil cylinder has a cushion collar, which is sleeved in the cushion position of a piston rod and can axially slide along the piston rod. In the oil cylinder cavity between an oil hole of the rod cavity and the terminal position of the piston end surface of the rod cavity during the piston extending movement, a sealing end surface of the rod cavity is provided, which can block the cushion collar and contact with the first end surface of the cushion collar to form a sealing surface. At least a throttle oil channel is provided between the cushion collar and the piston rod.

摘要： A cushion ring which is used between a rod-side cylinder head and a piston rod of a fluid-pressure cylinder and which is externally fitted on the piston rod to cushion a shock in the vicinity of the farthest extended end of cylinder includes a throttling groove that has a V-shaped cross section. The throttling groove extends from an appropriate position of the cushion ring to a rod-side end part and functions to throttle the flow of a working fluid flowing from a rod-side fluid chamber to an input/output port provided in a rod-side cylinder head. The throttling groove is provided at the outer periphery of the cushion ring. The throttling groove terminates at a rod-side end part with an end guide face that guides the working fluid toward a slantwise outward direction of the cushion ring.
