<p>There is disclosed a fluid pressure regulator having an integrated pick-off. Such a regulator comprises in a single block (1) the fluid circulation section which combines the regulator and the pick-off (12). In another block (2) which is integral with the first block, there is provided the control system which is comprised of a stepping motor (6) which is actuated by an external automatic device in order to obturate more or less an orifice (O) through a valve (10), a spring (9), a pusher (8) and a plug (7) so as to create a fluid leak (fr) in order to cause a fine variation of the utilization pressure (pu). The tightness between the two blocks (1) and (2) is obtained by means of a membrane (3). The plug (7) acts on the pusher (8) through said membrane. The invention applies to all devices using the pressure of a fluid in a hydraulic circuit and is particularly adapted to ink jet printers.</p> |
