Abstract: The pressure regulator comprises a valve with a slide member (5) whose displacements are controlled by the pressure prevailing in the control chamber (7). This pressure is adjusted by an obturator (11) of tubular shape which, in its upper position, places the chamber (7) in communication with the opening (4) of the fluid outlet. The fluid is admitted into the valve by an opening (2) and the displacements of slide member (5) permit adjusting the pressure in the opening (3) which supplies a user. The control chamber (7) is fed from the opening (3) through a conduit (20) with fluid whose pressure is already adjusted.

Abstract: The electromagnetic valve comprises a movable core (8) adapted to be drawn toward a fixed core (7) under the influence of a magnetic field of an excitation winding (5). The lower portion of the core (8) has a skirt (11) surrounding a cylindrical member (9) which is shaped such that the fluid moving from passage (2) to passage (3) will be directed radially relative to the skirt (11), so as to avoid the exertion of a force on the core (8) in its direction of movement.

Abstract: A valve for fluid comprises a body (1) of molded synthetic resin, this body (1) being surrounded by a casing (25) constituted by an extruded profile. This casing (25) has openings (30) in which are fixed plugs (31) having a screw-threaded bore and constituting connectors permitting connecting the valve to the tubing. Joints (34) between the plugs (31) and the valve body are provided to permit relative displacement between these parts without loss of sealing during displacement due to differences of expansion of the members as a function of temperature.
