Abstract

"PRESSURE FLUID FEEDING DEVICE THROUGH SEVERAL PUMPS MOVED BY A SINGLE MOTOR" comprising a plurality of pumps each equipped with a drive shaft, by means of a single drive motor of said pumps, equipped with a drive shaft outlet and with a tachymeter to measure the speed of rotation of the aforementioned output shaft, characterized by the fact that it comprises a plurality of actionable clutches, each equipped with an actuating fitting as well as a clutch interposed between the aforementioned output shaft and drive shaft of some pumps at least; further comprising a selector having at least one inlet fitting and outlet fittings at least equal in number to the number of pumps fitted with a clutch; or further comprising an inlet connection connecting the tachymeter to the selector inlet fitting; further comprising a plurality of outlet connections, which connect each connection to the outlet connection of the selector with the control fitting of one of the clutches, and whose selector controls in a known way and within a predetermined order, each clutch so that it decouples the drive shaft of the corresponding pump from the motor's output shaft and this in function of a reduction in the speed of rotation of the output shaft, detected by the tachymeter, the indication of which is transmitted to the selector.
