Abstract
The invention relates to a supply apparatus for two receiving means having a pressure summation device. A relief valve with a double control system is provided on a pipe shunted to the delivery pipe of the pump and has two control connections, a rod connecting the discharge member of the pressure summation device to the first of the said connections and a control pipe connecting that portion of the discharge pipe located between the connection of the latter to the delivery pipe and the relief valve to the second of the said connections. The invention is applicable to the realization of a supply apparatus with a pressure transfer system. PAC BACKGROUND OF INVENTION The present invention relates to an apparatus for supplying pressurized fluid to two receiving means with pressure transfer by means of a double control valve. Apparatuses for supplying two receiving means equipped with a pressure transfer system are already known. Such an apparatus is for example described in French Publication No. 2,218,007 of Sept. 6, 1974. Pressure transfer then takes place by using a first calibrated relief valve equipped with a single control system by the pressure of a fluid intermediate between th…
