    摘要: In a hydraulic control device (S) comprising a double-acting hydraulic consumer (V) which is actuable by pressure via two working conduits (4, 5) and secured in at least one working direction by a load holding valve (H) which is hydraulically openable and closable in a controlled way, further comprising a control pressure conduit (12) which is connected to a control connection of the load holding valve and selectively actuable, as well as a damping throttle (13) arranged in control pressure conduit (12), there is provided a valve (15, 15', 15", 15'", 15.sup.IV) which during the controlled closing movement of load holding valve (H, 6) is automatically responsive to a delay of the controlled closing movement which is caused by the instantaneous viscosity of the pressure medium and/or a too tight setting of damping throttle (13) and is critical as to the after-running of hydraulic consumer (V) under a load (F), with the valve switching in such a case to passage and bypassing damping throttle (13). The valve offsets the effect of a pressure medium which is too cold, and/or a setting of the damping throttle that is too tight for an intended damping action with respect to a controlled closing of the load holding valve, and it ensures the rapid closing of the load holding valve as is required for stopping and holding the load, in particular during a safety shut-off operation.

    摘要: An electromagnetically operable valve, comprising a coil and an electromat containing an armature, the armature of which impinges an actuating member connected to or forming an active member of the valve in operating connection and a lever mechanism arranged between the armature and the valve member for the step-up or step-down transmission of the stroke.In valves of this kind known from prior art a considerable expense in construction is incurred for the accommodation of the lever mechanism which offsets the savings with respect to the costs and the constructive area in long-stroke magnets; this is avoided by a novel construction incorporating the lever mechanism into the electromagnet and between the armature and the actuating member.

    摘要: The invention relates to a two-position switching valve having hydraulic f-holding properties and comprising a closure piston disposed in a flow path for displacement between an open position and a closure position for controlling a pressure between a maximum value and a minimum value, and operatively coupled to a control piston mounted for displacement in a housing. In known switching valves of this type, a creeping approach of respective switching points is scarcely avoidable under certain operating conditions. In accordance with the invention, a reliable switching function is achieved by forming the housing bore as a continuous stepped bore for slidably guiding therein a stepped piston consisting of a closure piston, a control piston, and a piston portion and by providing alternately openable and closable flow connections therein permitting an annular space between the closure piston and the piston portion to communicate with an annular chamber adjacent the control piston in the closure position of the closure piston, and the annular chamber to be pressure-relieved in the open position of the closure piston. These provisions result in the generation of a servo force for abrupt switch-over operation of the valve.

    摘要: The invention relates to a hydraulic control valve comprising a housing w a housing bore (2) formed therein, a control piston (3) being guided in said housing bore for sliding displacement between a neutral position (n) for zero-pressure through-flow and at least one control position (I, II), and further comprising a pressure inlet (6) opening in said housing bore (2), a through-passage (8) in said control piston (3), and a discharge outlet (7) communicating with said pressure inlet via said through-passage in the zero-pressure through-flow position. In a control valve of this type, particularly if employed in a high pressure hydraulic system, displacement of the control piston from a control position to the neutral position is hampered by unsatisfactory pressure compensation. In accordance with the invention, this undesirable effect is avoided by forming substantialy diametrally opposite said discharge outlet (7) a relief area (9, 9', 16, 17, 18, F26) compensating at least the effective area of said discharge outlet and being of substantially the same size as the discharge outlet and subjected to the same pressure as the latter. For ensuring effortless displacement of the control piston of an upstream control valve from its neutral position in a battery-type arrangement of a plurality of control valves even if a downstream control valve is in its control position, there is further provided an area (33) compensating the effective area of the relief area (9, 9', 16, 17, 18, F26) said compensating area communicating with return pressure at least in the neutral position (N).

    摘要: The invention relates to a hydromechanical tool or workpiece clamping apptus comprising at least one spring clamping cylinder connected to a release conduit and adapted to be hydraulically operated against a spring force to a release position, a pump connected to said release conduit and operable for a release operation, and a discharge conduit extending from said release conduit to a fluid reservoir and including a discharge control element for discharging the pressurized fluid from said spring clamping cylinder to said reservoir after deenergization of said pump. A known clamping apparatus of this type has a solenoid poppet valve disposed in said discharge conduit and operable to close said discharge conduit for the release operation and to be actuated to a flow-through position and maintained therein for the clamping operation. The solenoid valve is expensive and requires separate control means. In contrast thereto, the invention provides the use of a discharge control element in the form of a simple bypass shutter the flow resistance of which at a constant output flow rate of the pump is greater than the pressure required for overcoming the spring force in a release operation.

    摘要: This invention relates to a hydraulic device comprising at least one adjuble working, control or regulating member between a pressure source (3) and the flow path of an outlet (5,R), said member establishing an unrestricted connection to a passage in one position with the pressure medium which is present flowing out via said connection by expanding. In the case of high working pressures and/or great quantities of delivery, a loud noise develops in such hydraulic devices throughout the whole flow path of the outlet when the jet flows out. According to this invention, this is prevented by a jet disturbing means (6) being arranged after said member and having a jet disturbing element (31) which is adapted to be biased, which is directed to the jet and adjustable in dependence of the pressure to be reduced from a ready position into working positions in which it increasingly disrupts the jet, said jet disturbing element (31) automatically taking up its ready position as soon as the pressure to be reduced approximately corresponds to the pressure behind the jet disturbing means (6).
