Abstract (en)
Station for supplying pressurized gas to tanks, in particular to tanks installed on vehicles, includes an electric unit (1), fed by an electric main (L) and aimed at supplying at the outlet, in accordance with the control and command signals of a command and control unit (C), to which it is connected, an electric voltage of adjustable effective value (V 0 ) and frequency (f 0 ). An electric motor (M) is powered by the electric unit. A compression unit (Y) is operated by the shaft of the motor (M), and its aspiration is connected to a low pressure gas main (AM). A reference tank (P) is connected to the delivery of the compression unit (Y). A device (D) for delivering the pressurized gas is connected to the reference tank (P), and it has connectors (U1, U2, ..., Un), which can be connected to as many users (K). At least one sensor (R) for measuring pressure inside said tank (P) is connected to the command and control unit (C), which compares a selected pressure value with the pressure value measured by the sensor, and commands the electric unit (I) in relation to the pressure difference between the selected and measured values, with a consequent activation of the compression unit (Y), in which the working cycles in time unit depend on the effective value (V 0 ) and frequency (f 0 ) of the motor (M) power voltage.
