Abstract:
A hydraulic actuator return pressure fluid recovery system, comprising:a plurality of fluid recovery circuits associated with a plurality of hydraulic actuators for accepting flows of a hydraulic pressure fluid returned from said actuators;a main fluid recovery circuit; anda selector means for permitting at least one of said plural fluid recovery circuits selectively to communicate with said main fluid recovery circuit, whereinsaid selector means is adapted to selectively establish a first state in which any one of said fluid recovery circuits solely lies in fluid communication with said main fluid recovery circuit and a second state in which more than one of said fluid recovery circuits lie in fluid communication with said main fluid recovery circuit, and wherein, when a first fluid recovery circuit of said fluid recovery circuits is in fluid communication with said main fluid recovery circuit, said selector means prevents a second fluid recovery circuit of said fluid recovery circuits from being in communication with said main fluid recover circuit.
