  • Publication number: 20210207627
    Abstract: The invention relates to a control device for a hydraulic consumer (22), susceptible to vibrations, comprising a valve (24) having a control spool (40), which can be controlled by means of an actuating device (46), wherein the valve (24) has a pressure supply port (P), to which a pressure compensator valve can be connected, which can be supplied with pressure fluid from a pressure supply device, wherein the actuating device (46) has a motor (74) and wherein a load-pressure-dependent force on the control spool (40) can be generated by means of a control device (66). In accordance with the invention, this force at the control spool (40) acts on an electronic motor controller (208) of the DC motor (74), which detects a change of the force and acts as a damping of the vibrations of the consumer (22) against this change of force.

  • Publication number: 20210199206
    Abstract: The invention relates to a valve, which is characterized in that between a neutral position (38) of a control spool (STS) and one of its end positions (34, 42) a regeneration position (36) is provided, in which two utility ports (A, B) are interconnected in a fluid-conveying manner, or a floating position (40) is provided, in which these utility ports (A, B) are interconnected in a fluid-conveying manner. The invention relates to a further valve, which is characterized in that by a further motion of the control spool (STS) in the same direction, as that, in which a fluid connection is established between the utility ports (A, B) starting from the neutral position (38), this fluid connection is interrupted.

  • Patent number: 11015723
    Abstract: A valve includes a valve housing (33), which has at least one service connection (A, B), a pressure supply connection (P) and a return connection (T). In the valve housing (33), a control slide (STS) is guided so as to be movable longitudinally to control these individual connections. The supply pressure, which is applied to the pressure connection (P) to control a consumer (10, 12), connected to the service connection (A; B), is guided across at least one control side (56) of the control slide (STS) via an orifice plate (54) and a control channel (50). The control side (56) is positioned in a control chamber (58) in the valve housing (33) such that it can move. The control chamber (58) is connected to the return connection (T) via an additional orifice plate (59).

  • Patent number: 11009051
    Abstract: A valve includes a valve housing (2) for transport of a heatable fluid such as hydraulic oil. The valve housing has at least one utility connection (A, B), at least one pressure supply connection (P), and at least one return connection (T1, T2). A control slide (6) is guided in the valve housing (2) in a longitudinally displaceable manner. In at least one position of the control slide (6), the pressure supply connection (P) is at least partially separated from the utility connection (A, B), and the heatable fluid arrives, proceeding from this pressure supply connection (P) and via a heat-emitting connection in the control slide (6), at the at least one return connection (TI, T2) as a loss volume flow. The loss volume flow serves as a heat source and heats at least regions of the control slide (6).

  • Patent number: 10914325
    Abstract: A valve apparatus for influencing a flow of medium between a supply port (38) and a pressure port (40) has a valve device (10). In one closed position, the valve device blocks the connection between the supply port (38) and the pressure port (40). The valve device opens this connection in one opened position, in which the pressure port (40) is connected to at least one of two medium chambers (62, 80) by a respective fluid channel (64, 82). One fluid chamber (64) comprises a fluid duct (68) in the valve slider (22). The other fluid channel (82) has a further fluid duct (84) that is separate from the fluid duct (68). In one of the opened positions of the valve slider (22), the further fluid duct (84) opens at one end (92) into the medium chamber (80). In every displacement position of the valve slider (22), the further fluid duct (84) is permanently connected at the other end (94) to the pressure port (40).
