摘要： A control circuit for a pressurized fluid engine comprising a first main conduit and a second main conduit for connection to a fluid engine, means for connection to a main source of pressurized fluid, means for connection to a return for nonpressurized fluid, a supply selector having at least two positions, which, in its first position, connects the first conduit to the main source connection means and the second conduit to the fluid return connection means and, in its second position, blocks the first and second main conduits at its position, means for connection to a secondary source of fluid, a secondary conduit connecting the secondary source connection means to the first main conduit, a non-return valve in the secondary conduit permitting passage of fluid from the secondary source connection means to the first main conduit, a distributor having two positions, arranged in the first and second main conduits, defining two separate portions of each of the main conduits and which, in its first position, places the two portions of each of the main conduits in communication and, in its second position, isolates the two portions of the respective main conduits from each other, a connection conduit which, in the second position of the distributor, connects those portions of the first and second main conduits to be connected to the engine, a discharge conduit which connects the connection conduit to nonreturn connection means, a main restriction in the discharge conduit, and a secondary restriction in the portion of the connection conduit between the union of the connection conduit to the first main conduit and to the discharge conduit.
