Abstract

Pressure control device for pneumatic machines, which being specially designed to interrupt the pneumatic supply when the level of pressure reaching the machine falls below a predetermined level, is characterized in that it consists of a valve body (1), with an axial conduit (3) for passage of fluid and with a radial hole (3 ") in communication with the previous one, of which a cylinder (4), of equal internal diameter, is also extending radially, playing in the set constituted through the radial hole (3 ") and the cylinder (4) a shutter (6) associated with an axial rod (7) that passes through the end base of the cylinder (4) and that is externally terminated in a handle (8), it being provided that between the obturator (6) and the closed end of the cylinder (4), preferably in a coaxial arrangement with respect to the stem (7), a spring (10) is established, suitably tared so that after a manual valve opening, actuatingon the lever (8), against the spring (10), the obturator (6) is kept in an open position when the pressure inside the valve body (1) corresponds to the nominal working pressure, and to cause the automatic valvular closing when said pressure falls below a pre-established level for the effect.
