Problems solved by technology

However, due to the slow closing characteristic, which in turn prevents a quick response of the valve, the known valve is not suitable for many applications in which a fast response characteristic of the valve components is important

Embodiment Construction

[0027] figure 1 A schematically simplified longitudinal section of a valve device is shown, which has a valve housing 4 in which a hollow cylindrical valve part 6 is guided in a longitudinally displaceable manner. exist figure 1 shows the valve part 6 in abutment against the valve closing part 10 in the closed position under the action of the accumulator 8 in the form of a compression spring as part of the actuating mechanism 8, 14, in which position , the valve part blocks a fluid path through the valve arrangement between the fluid input E and the fluid output A along a predefinable flow path for a fluid, such as a hydraulic medium (oil).

[0028] In at least one open position not shown in detail in the drawings (in this open position, the valve part 6 actuated by the magnetic actuating mechanism 14 as another part of the actuating mechanism 8, 14 is in its position against the action of the pressure spring 8 out of engagement with the valve closing member 10 in the axial ...

Abstract

The invention relates to a valve device having a valve housing (4), in which a hollow valve part (6) is guided in a longitudinally displaceable manner, which valve part, controlled by an actuating device (8; 14), in at least one open position clears the fluid path for a fluid through the valve between a fluid inlet (E) and a fluid outlet (A) along a predeterminable flow path, and blocks said fluidpath in a closed position, in which the valve part (6) is in contact with a valve closing part (10) from which the valve part retracts in the open position(s). The valve device is characterized by the provision of at least one flow guiding device, which causes an at least partial reversal of direction in the flow path for the fluid flowing out of the valve part (6) as soon as the valve part assumes an open position.

Description

technical field [0001] The invention relates to a valve arrangement having a valve housing in which a hollow valve part is guided in a longitudinally displaceable manner, which valve part is released in at least one open position when actuated by an actuating mechanism passing through the valve along a fluid path along a predeterminable flow path for the fluid between the fluid input and the fluid output and blocking said fluid path in the closed position in which the valve The part is in contact with the valve closing part, which is lifted from the valve closing part in the corresponding open position. Background technique [0002] A coaxial valve of this type is known from DE 101 21 616 A1, which has a valve housing in which a hollow valve part in the form of a tube is guided in a longitudinally displaceable manner, the valve part It cooperates with an end-side valve seat which is arranged in the valve closing part. Furthermore, for moving the hollow valve part, a magnet...
