摘要： Valve assemblies (320; 420)are provided in a track tensioning system or in other applications. The valve assemblies allow pressurized fluid (grease or hydraulic fluid from a power machine) to be introduced or evacuated from the same port. The valve assemblies use either a single check ball or poppet configuration, or a dual check ball or poppet configuration which are moveable from a first configuration, in which fluid is blocked in one direction while allowing flow in the other direction, to a second configuration where the reverse is true. A track tensioning element (300; 400; 600) includes piston retaining features (515; 550) which retain a piston (505) within a track tensioning cylinder tube (510). A track tensioning element can also include a no-pre-load spring (605) positioned in-line with the tensioning cylinder (610). Disclosed track tensioning systems and track tensioning elements can, in various embodiments, utilize any combination of all or some of the disclosed features.

摘要： A hydraulic circuit for an actuator that has a piston and piston rod that will move a load in a first direction, and which can be externally loaded in an opposite direction, includes a flow compensated valve between the actuator and a control valve. When the piston in the actuator is moved in the second opposite direction under the external load and the rate of flow of fluid out of the actuator through the flow compensated valve exceeds a selected rate, an orifice is introduced in the flow path to restrict flow from the actuator.

摘要： A lower control system serves to regulate the flow rate of lifting jack oil, and is installed between a reverse flow valve (5) and an inner oil chamber (101) to regulate the oil flow from the inner chamber (101) to an outer chamber (102), the lower control system comprising an outer valve body (1), a steel ball (2), a spring (3), and a throttle body (4), the throttle body (4) having a tapered portion (41), formed at its front end, and at least one throttling slot way (411) and one lateral slot way (42), formed respectively on the tapered portion (41) and the circumferential wall thereof, such that, when the jack is not loaded, the reverse flow valve (5) can lift the steel ball (2) so that oil swiftly flows by the throttle body (4) through the lateral slot ways (42) to complete the reverse flow, and, when the jack is loaded, oil gently flows by the throttle body (4) through the throttling slot ways (411), leading to a reduction of oil flow rate and a slower descending of the jack.

摘要： A bidirectional check valve controls movement of fluid. A valve body has an opening (116), a further opening (117) and a passage (115) connecting the opening and the further opening. A poppet (104) is disposed within the passage of the valve body, and a spring (110) is coupled to the poppet. A further poppet (106) is disposed within the passage formed in the first mentioned poppet, and a further spring (105) is coupled to the poppet and to the further poppet. When fluid passing through the opening in the valve body exerts a force on the poppet that is greater than the spring force, the further portion of the outer surface of the poppet is directed away from the further portion of the wall of the passage and permits the fluid to flow from the opening in the valve body through a channel and to the further opening in the valve body. When fluid passing through the further opening in the valve body exerts a force on the further poppet that is greater than the further spring force, the further portion of the outer surface of the further poppet is directed away from the further opening in the valve body to open a further channel in the poppet and permit the fluid to flow from the further opening in the valve body through the further channel, at least one opening in the further poppet, a further passage in the further poppet, a further opening in the further poppet and an opening in the poppet to the opening of the valve body.

摘要： A de-linking assembly includes an actuator defining a chamber and an inlet, a piston slideably disposed within the chamber, link coupled to the actuator, and a ram disposed between the piston and the link. The link defines a stress concentration features and a load point on a side of the link on a side of the stress concentration feature opposite the actuator. The ram is seated to the piston and against the load point such that air introduced into the chamber through the inlet applies force to the piston and ram sufficient to sever the link by inducing stress in the stress concentration feature.

摘要： The present invention comprises a poppet (11) which functions as a load check valve, and a pressure balancing slide (9) wherein the poppet (11) functions inside the body at the same time and a spring which separates them from each other. The present invention relates to a valve system (1) having load checking and pressure balancing functions in hydraulic fixtures which balances pressure when the flow passage is from the orifice to the client, and which functions as a load check valve when the flow passage is from the client to the orifice, in other words from the client to the pump. By means of the present invention, less number of pieces is used, simpler casting methods are applied and process duration is shorter and the functions of load check valve and pressure balancing can be realized.

摘要： In this invention, check valves (11), opportunely modified with position transducers(12), are used to sense the flow rate supplied to each consumer. An electronic control device (16) sets the inlet pressure and the opening of the spool in each working section (7) in order to regulate sensed flow as a function of electrical input signals. Unlike previously known load-sensing control systems, no pressure signals have to be managed to supply constant flow rate to one or more consumers regardless of their load pressure
