FLUSHING COCK (VERSIONS) Russian patent published in 2009 - IPC E03D3/04 

FIELD: personal use articles.

SUBSTANCE: invention relates to the field of sanitary engineering. The flushing tap is composed of an inlet and an outlet nipples and an inlet and an outlet cavities with a bypass port arranged between them. The cylindrical-shaped section of the inlet cavity contains a piston (coaxially positioned and interacting with the bypass port seat). The device is additionally equipped with a threaded plug with a gasket (mounted onto the housing on the side of the inlet cavity cylindrical-shaped section) and the cock actuator mechanism. The cock actuator mechanism consists of a spring-loaded button mounted onto the housing on the side opposite to that of the piston installation and equipped with an axle that has a threaded hole; the axle is fitted in a guide arranged inside the housing and equipped with a pressure-tight sealant element. The rod is represented by a screw whose head is contained inside the piston so that to ensure a clearance maintenance and to enable axial motion towards the plug. The second design version envisages the cock actuator mechanism being equipped with a spring-loaded handle mounted onto the housing on the piston installation side and equipped with an axle that is fitted in a guide arranged at least inside the plug and equipped with a pressure-tight sealant element. The adjustable length rod is represented by a screw whose elongated head is partly contained inside the piston so that to ensure a clearance maintenance and to enable axial motion towards the plug.

EFFECT: enhanced structural reliability.
