Embodiment Construction

[0034] In FIG. 1 , the packing element 1 is placed in the valve housing 2 such that it is movable between a second surface 4 formed in the valve housing and a restriction member 6 . When properly arranged geometrically, the packing element 1 cannot turn sideways in the confined space thus created. The first surface 3 of the packing element 1 is in contact with the second surface 4 of the valve housing 2, as Figure 1B and 1C shown. Subsequently, in Figure 1A , Figure 1B and Figure 1C The breakage 5 shown in various forms in FIG. 2 ensures that a given degree of flow is achieved between the contacting first surface 3 and second surface 4 .

[0035] exist Figure 2A , a similar packing element 1 can be seen in which a damage 5 is formed in the first surface 3 of said packing element. In this example, the packing element 1 is made of elastic material. The breakage 5 is formed as a radial or approximately radial through passage. Due to the pressure difference on both si...

Abstract

The present invention provides a control valve with profiled packing element for making bidirectional flow-through with asymmetric intensity possible in a flow area. The packing element (1) has a first surface which can be abutted against a second surface in the valve housing (2). The packing element (1) has a first position in which said first surface (3) and said second surface (4) abut against one another, and a second position in which said first surface (3) and said second surface (4) are distant from one another. At least one of the surfaces (3, 4) is provided with a damage (5) by means of which when said packing element (1) is in its first position a first cross-section of flow is ensured between said abutting first and second surfaces (3, 4), which is smaller than a second cross-section of flow ensured by said packing element (1) when it is in its second position.

Description

technical field [0001] The invention relates to an arrangement suitable for use in a control valve comprising a first and a second surface for closure and the invention relates to a control valve of this type. In particular, the invention relates to a control valve with a profiled packing element for making it possible to achieve a bidirectional flow-through with an asymmetrical intensity in the flow area, Wherein the packing element is provided with a first surface which can abut against a second surface formed in the valve housing. Naturally, when eg used in a piston system, this asymmetrical flow rate enables control of the movement and speed of movement of components connected to said piston, eg closure elements, brakes, shock absorbers. Background technique [0002] Solutions suitable for controlling the flow of fluid materials by means of pairs of abutment surfaces which on the one hand prevent the flow area from being clogged by dirt present in the flowing material a...
