Embodiment Construction

[0031] Figure 1 to 11 The switching valve 1 configured as a 4-position 3-port valve is shown. The inlet of the switching valve 1 is, for example, connected to a water input device, and the outlet of the switching valve 1 is selectively connected to a bathtub outlet fitting, a flexible hand-held sprayer, or, for example, a fixed spray head.

[0032] Switch valve 1 has Figure 1 to 4 The valve housing 2 shown in detail in, the valve housing has two inlet holes 3, 3'serving as inlets and three outlet holes 4, 5, and 6 serving as outlets. The valve housing 2 can be constructed in one piece or in multiple parts; the valve housing 2 here is constructed in two parts and has a fitting housing 201 (see Figure 5 to 8 ) In the cartridge 2b and the threaded joint 2c used as the end side terminal of the accessory housing 201 (see Figure 1 to 4 ). Among the three discharge holes 4, 5, 6, each of the discharge holes can be selectively arranged in the inlet holes 3, 3'by using a switching sha...

Abstract

The invention relates to a changeover valve with: a valve housing; two sealing elements; a changeover tube, wherein an axial adjustment movement of the changeover shaft can be transmitted to at least one of the two sealing elements, so that: both seals The element bears with its outer, surrounding sealing surface against a corresponding sealing surface of the valve housing delimiting the fluid passage, and one of the sealing elements closes the adjacent circumferential end face edge of the transition tube with its inner, surrounding sealing surface, The other sealing element is kept at a distance from the other peripheral end face edge of the transition tube which serves as a fluid passage; or the two inner surrounding sealing surfaces of the sealing element bear against the adjacent peripheral edge of the transition tube One of the sealing elements impinges with its outer, surrounding sealing surface an adjacent corresponding sealing surface delimiting the fluid passage, while the other sealing element is spaced apart from its associated corresponding sealing surface delimiting the fluid passage.

Description

Technical field [0001] The invention relates to a switching valve, with which different outlets of the switching valve can be selectively arranged at the inlets of the switching valve. Background technique [0002] Even in the sanitary field, a variety of structures are known for switching valves, which are used to selectively pass the water taken from the pipe network to the bathtub outlet or to the spray head. In addition, a switch valve designed as a 4-position 3-way valve has been implemented, which has three outlets, of which the first outlet is connected to the hand-held sprinkler, the second outlet is connected to the fixed shower head, and the third outlet can be connected to the bathtub water injection accessory on. [0003] In the known 4-position 3-way valve, one of the three outlets can mostly be connected by means of a rotary or translational switching movement. If it is necessary to give priority to an outlet in a certain operating state, this is achieved by hydraul...
