Title:
BALLCOCK-VALVE
Document Type and Number:
WIPO Patent Application WO/2020/197447
Kind Code:
A3
Abstract:
Unlike known ballcocks, the proposed ballcock-valve is a half-turn fitting with a separate phase for adjusting the flow area by the contactless rotation of a shut-off member, and a phase for sealing the clearance by the parallel micro-displacement of the shut-off member orthogonally to the plane of the seat. This valve-style contact permits the use of maximum surface stresses that are up to 11 times greater than standard and provides the known inherent advantages of a valve over a ballcock, without the inherent disadvantages of a valve. More particularly, it provides increased threshold values in terms of working pressures and temperature, a longer service life and increased reliability and safety, while providing full flow and minimal flow resistance. The mechanism is structurally simple, capable of being reproduced and has a significantly lower peak control torque and drive power due to the absence of sliding friction against the seat and the presence of a built-in eccentric booster.
