INVENTOR: MARCEL BOSCHUNG INVENTION: AUTOMATIC VALVE FOR CONTROLLING THE PASSAGE OF AN IN-FEED PRESSURE FLUID TO BE DELIVERED IN PREDETERMINED QUANTITIES INTO A RECEIVER ABSTRACT OF THE DISCLOSURE Automatic valve for controlling the passage of an in-feed pressure fluid to be delivered in predetermined quantities into a receiver. The automatic control valve comprises two tandem-joined piston cylinders. The first piston cylinder comprises two cavities of different volumes. The second piston cylinder comprises only one cavity. There is placed a piston in each of the cavities of the first piston cylinder, which pistons have different diameters and the circumference surfaces are spaced from the inside walls limiting the respective cavities of the first piston cylinder. The cavity of the second piston cylinder comprises a shock- absorbing device connected with a piston rod carrying also both the pistons placed in the cavities of the first piston cylinder. The piston placed in the cavity of the bigger volume of the first piston cylinder is fixed to the piston rod, whereas the piston placed in the cavity of the smaller volume of the first piston cylinder is shiftable on the piston rod between two limit stops.
