Embodiment Construction

[0022] The cleaning valve shown in axial section in FIG. 1 comprises a valve housing 1 which is closed by means of a base 2 in its bottom part. The base 2 comprises a plurality of outlet openings 3, and an inlet opening 4 in the middle. The valve housing 1 is inserted onto a fitted housing in which corresponding channels are provided. For sealing against the fitted housing, a seal 5 is provided.

[0023] On the base 2 of the valve housing 1 , a fixed ceramic disc 7 is arranged above the seal 6 , which ceramic disc is often also referred to as a distribution disc. This distribution plate 7 has a passage opening 8 which communicates with the water outlet 3 . The distribution plate 7 is also characterized by two central cutouts, which communicate with the water inlet 4 . These intermediate cutouts are not visible in the cross-section of FIG. 1 .

[0024] Above the distribution disc 7, a first movable control disc 9 is arranged in the middle. This movable control disk 9 can b...

Abstract

Disclosed is a disk-type pilot valve which encompasses both throughput control and a distribution function for distributing penetrating water to one of several outlets (8, 3). In order to allow one respective movable control disk that is to be actuated separately to cooperate with a joint stationary distribution disk (7) for both controls (9, 15), pressing of the two movable control disks against the distribution disk can be adjusted and regulated separately. Two actuating elements (14, 19), one of which is disposed around the other one as a sleeve, are used for actuating.

Description

technical field [0001] The invention relates to a valve in which the possibility of closing and dispensing of water to one of several dispensing outlets are combined. Background technique [0002] Such valves are well known. Typically, there is a single actuator (or drive) with which the output and select water outlets can be actuated by the valve. Since most cleaning (or pumping) valves are made as ceramic disc valves, a problem arises in that the volume of the ceramic disc increases as the number of dispensing outlets increases. Consequently, due to the increased friction, the force required to actuate the valve increases. This applies in particular during the combined closing and dispensing activities performed in the same pair of control discs in order to reduce the overall height of the valve. [0003] A valve with which several outlets can be closed and distributed is known (see patent document US6357476). Since the pivoting control dial of one control device inter...
