Control disc valve for plumbing fittings - has brake device with recesses and projections to control the amount of water flow and allow unimpeded opening movement of control disc.

摘要

The brake device (10.1,10.3,12.1,12.2) which counteracts the translation of the movable control disc (8,9,10) at least in a translation section directly in front of the fully closed position has one or more recesses and projections formed alternately on the movable control disc (8,9,10) and on the surfaces opposite the housing (1,12) in the translation direction. The recesses and projections (10.1,12.1) each form a brake chamber in the translation section with the housing and movable control discs which is immediately in front of the fully closed position. The recesses can be grooves formed in the movable disc and the projections can be webs formed in a first component connected to the housing. The axis of movement of the brake chambers is parallel to the contact plane between the locally fixed and movable control discs (5,8). USE/ADVANTAGE - Control disc valve for plumbing fittings has functionally reliable brake device with simplified cost-effective construction.
