GROUP OF HEIGHT-ADJUSTABLE FLUSHING VALVES FOR FLUSHING TANK Russian patent published in 2015 - IPC E03D1/14 E03D1/34 

FIELD: machine building.

SUBSTANCE: invention relates to the valves for flushing lavatories or urinals with flushing and disinfecting devices. The group of height-adjustable flushing valves (1) for the flushing rank continues along the axis (A) and contains main casing (5) with movable gate (2), support (7) supporting the gate activating gear (4), gear (8) of height adjusting to change distanced between the support (7) and main casing (5). Gear (8) contains released work element (32). The work element (32) is located around the casing (5) and is connected with casing (5) such that to have possibility of axial connection with the casing (5). The gear (8) contains pole (30) parallel with axis (A) supported by the support (7). The pole (30) slides in the guide (31) created in the casing (5). The work element (32) is made inclined rotated relatively to the casing (5) around the axis (A) for selective accepting of the locked position and unlocked position. In the locked position the work element (32) axially engages the pole (30) and axially connects the combined support (7) and casing (5). In the unlocked position the work element (32) does not engage axially the pole (30), and support (7) is axially sliding relatively to the casing (5).

EFFECT: simple production and installation of the valves.
