AUTONOMOUS HYDRAULIC UNIT

Abstract

Autonomous hydraulic unit comprising a liquid inlet (1); a flow meter (2) which is jointly attached to an inlet (3) of a compression chamber (4) of a pump (5) where a piston (6) injects the compressed liquid through a nozzle (7) into a heating chamber (8).

A plastic body (9) integrates in one piece the compression chamber (4), a self-priming valve (10) and a safety valve (11). A heating element (12) contained within a body (9) determines with a disk (14) the heating chamber (8) where the temperature of the liquid injected by the piston (6) is raised in its passage towards the outlet (13).
