Valve device for controlling a fluid flow and flow control valve

Valve device. 2. ... Hydac Fluidtechnik Gmbh


The invention relates to a valve, in particular a proportional pressure regulating valve, comprising a valve piston (12) which is longitudinally movable in a valve housing (10) for alternately releasing and connecting a user connection (a) to a pressure supply port (p) or a tank connection (t), which can be actuated by means of an actuating magnet (14) and which produces a dither signal during operation, characterized in that the valve piston (12) reaches a floating position within the valve housing (10) by means of a hydraulic lift limitation for the receipt of the dither signal.. . ...

Pressure-regulating valve

A pressure-regulating valve having a valve piston (i0) which is subjected to the action of an energy store and which is guided in longitudinally displaceable fashion in a valve housing (12), which valve housing has ports such as a supply port (14), a utility port (16) and a tank port (18), which ports can be actuated, by way of a control part (20) which closes with a sealing action, such that, in the case of a fluidic connection from the supply port to the utility port, a pressure reduction function is realized, and in the case of a fluidic connection from the utility port to the tank port, a pressure-limiting function is realized, characterized in that the control part (20) has a control rod (22) with two control bodies (24, 26) held spaced apart from one another, of which control bodies one (24) controls at least the fluidic connection between supply port (14) and utility port (16), and the other control body (26) controls at least the fluidic connection between utility port (16) and tank port (18).. . ...

Pressure-limiting valve

A pressure-limiting valve with feed function, comprising a valve housing (20) having at least two connection points, in particular in the form of a working connection (a) and a tank connection (t), and having a spring-loaded pressure-limiting valve piston (22) which is mounted such as to be longitudinally movable in the valve housing (20), and having a spring-loaded non-return valve piston (56) for the implementation of the feed function, is characterized in that the non-return valve piston (56) is designed as a hollow piston and is mounted such as to be longitudinally movable in the valve housing (20).. . ...

Valve device

The invention relates to a valve device having a valve housing, and comprising a main piston (4) that is arranged in an axially slidable manner in a piston bore of the valve housing (2), via which a first consumer connection (a) and a second consumer connection (b) can be alternately connected to a pressure connection (p) and a tank connection (t1, t2) by way of the action of a first magnetic actuating system (6) and a second magnetic actuating system (8) and comprising two pilot pistons (14, 16). The invention is characterized in that in an actuated state of the respective pilot piston (14, 16), the main piston (4) follows the movement of said pilot piston (14, 16) due to the force ratio adjusting itself thereon, thus actuating the fluid-carrying connection between the pilot chamber (10, 12) of said pilot piston (14,16) and the assignable tank connection (t1, t2) such that pilot oil flows.. ... Hydac Fluidtechnik Gmbh

Pilot-operated directional control valve

The invention relates to a pilot-controlled directional control valve, in particular a directional poppet valve, comprising a valve housing (10), at least three fluid connection points (12, 14, 16) with a main control stage (18) and a pilot control stage, characterized in that a further fluid-controlling intermediate stage (22) is arranged between the main control stage (18) and the pilot control stage (20) and that the main control stage (18) comprises a longitudinally movable main control piston (24) and the pilot control stage a longitudinally movable pilot control piston (26).. . ... Hydac Fluidtechnik Gmbh

Proportional pressure control valve

Disclosed is a proportional pressure control valve with a control piston (12) guided in a longitudinally movable manner in a valve housing (10), said control valve serving, by means of an actuating system (14), to selectively connect the connection points present in the valve housing, such as a pressure supply connection (p), a consumer connection (a) and a tank or return connection (t), wherein a first characteristic curve is produced between a control signal of the actuating system (14) and the flow volume or the control pressure (p), in relation to the consumer that can be connected to the consumer connection (a), wherein a second characteristic curve is produced for the consumer that can be connected to the consumer connection (a) of the valve housing (10) by means of a control device (65) after running through the first characteristic curve, the second characteristic curve differing to the first characteristic curve.. . ... Hydac Fluidtechnik Gmbh

Compact unit

The invention relates to a compact unit, at least consisting of an electric motor, which is accommodated in housing parts (7, 55) of a unit housing (45) and which drives at least one hydraulic pump and gives off heat at the same time, an air heat-exchanging device, and a fan (19), which can be driven in order t o produce an air flow. The compact unit is characerized in that a flow-conducting device (47, 55) that divides off from the air flow at least a first partial flow flowing around the electric motor and a second partial flow flowing to the heat-exchanging device is present in the unit housing (45), or that, arranged in series, the air flow first flows against the electric motor and then the heat-exchanging device, or that the incidence of the air flow occurs at least partially in the reverse direction.. ...
