Embodiment Construction

[0019] figure 1 A section through a multi-way stopcock with a base body 10 is shown which has a total of four pressure connections A, B, P and R in the exemplary embodiment shown. It is thus possible to connect the connection P to the pressure connection of the hydraulic system and the connection R to the return connection of the hydraulic system in a known manner. The connections A and B can be connected to the cylindrical piston connection (Zylinderkolbenanschluss) and the annular space connection (Ringraumanschluss) of the hydraulic cylinder.

[0020] In addition, in figure 1 An additional connection 12 is provided for the pressure limiting valve. Because for most applications the overpressure Can only be present on one side, so this side can be connected to the side of the overpressure valve. Such as figure 1 As shown, the joint of the overpressure valve 12 is connected to the joint A.

[0021] A connection element 20 is rotatably accommodated inside the base body, ...

Abstract

The selector valve has a closure element (20) provided with through channels (16, 18) and rotatably mounted in a base body (10) to make a connection among connectors (A, B, P, R) that are provided in the base body. The closure element is mounted in a sealing body (14) with a ring opening and through-holes (22, 24, 26), and the sealing body includes a ring in an opened position. The through-holes are provided with a sealing element. A release opening is partially sealed after mounting the closure element in the sealing body. An independent claim is also included for a method for mounting a selector valve.

Description

technical field [0001] The invention relates to a substrate with A multi-way stopcock (Mehrwegehahn) with a through-channel connecting element (Schlieβelement) is rotatably accommodated in the base body in order to establish a connection between the connections provided in the base body. Background technique [0002] Different realizations of such multi-way stopcocks are known. Especially in underground constructions, such a multi-way cock can be designed and used as a ball cock, for example, in order to drive the hydraulic cylinder in two directions and also hold it in one position. Since each sealing seat (Dichtsitz) pertaining to an individual straight-through channel (Durchgangskanal) is a separately produced component, the construction of the known spherical plug valves or multi-way plug valves associated therewith is relatively large. In other embodiments, however, the sealing seat or the sealing gasket is damaged relatively quickly in this case despite the relative...
