Hydraulic distributor for heating or air conditioning installation, has adjustment unit provided between lateral openings whose axes are located in radial plane perpendicular to radial plane containing axis of adjustment unit

摘要

The distributor has a tubular body (8) comprising two axially movable lateral openings (11, 12) and end clamps (9, 10) for connecting the body to a return pipe (3) of an installation. A piston (14) constitutes an adjustment unit that is provided between the openings, where axes (B, C) of the openings are located in a radial plane (P1) perpendicular to a radial plane containing an axis (D) of the unit. The piston is connected to an adjusting spindle (20), which projects from an annular end surface (26) of a tubular projection (15) of the body with preset distance when the spindle moves back.
