THERMOSTATIC WATER MIXER TAP AND METHOD OF MANUFACTURING SUCH WATER MIXER TAP Russian patent published in 2012 - IPC F16K11/44 G05D23/13 

FIELD: machine building.

SUBSTANCE: thermostatic tap (1) comprises a body (2) of the water mixer tap of tubular shape, a thermostatic element (3), which forms a pre-assembled complex inserted inside the body (2) of the tap, and facilities (6, 7) of shell fixation in the body (2) of the tap. The thermostatic element (3) comprises a hollow shell (4) of plastic material, where thermostatic facilities (5) are installed to adjust temperature of a medium (M) going out of an element and produced by means of mixing of an incoming cold medium (F) and incoming hot medium (C). Fixation facilities comprise a screw (7) at one side, including a rod (71) with helical thread and an expanded end head (72), and on the other side there is a rigid part (6). For simple and rigid fixation in the body (2) of the tap, the rigid part (6) is movably inserted between the body (2) of the tap and the shell (4) along the axis of displacement (Z-Z), the transverse longitudinal axis (X-X) of the body (2) of the tap and is kinematically joined with the shell (4) simultaneously in direction of the axis of the body (2) of the tap and rotation around this axis. The rigid part (6) is equipped with a hole with helical thread (63) with the centre along the axis of displacement, which opens to the surface (62B) of the rigid part facing the body (2) of the tap. The rigid part (6) is arranged as capable of interaction by means of screwing of a rod (71) with helical thread of the screw (7) for displacement of the rigid part (6) to adjacency to the surface of the support against the inner surface (2A) of the body (2) of the tap, when this screw is introduced outside the body (2) of the tap via a transverse hole (21), crossing the body (2) of the tap and smaller than the head of the screw (72). There is a method to make the specified water mixer tap.

EFFECT: simplified maintenance of a tap that does not require long and complicated adjustment and its simplified manufacturing.
