Abstract

Fluid distributor device for control by means of a pumping group for concrete and the like, consisting of a pair of single-acting piston pumps, which operates in phase opposition and whose pistons are actuated by a pair of single-acting hydraulic hammers , pumps that are placed alternately in communication with the suction path to the concrete supply duct, and with the compression path to the outlet pipe and vice versa by means of a valve, preferably a register valve, these hammers being connected to each other by means of of a conduit that puts into communication the chambers of the cylinders located above their pistons, while in the vicinity of the heads below said pistons, the hammer cylinders are provided with a hole for fluid entry during operating route of the corresponding ram and for unloading on the opposite route, a hydraulic circuit that can one in communication with the fluid supply pump in particular oil, with the hammer light in the aspiration phase, while the other hammer light is put in communication with the discharge through a switching valve and a distributor device, characterized in that said distributor is made up of a pair of single-acting hydraulic cylinders, which can also be non-parallel and have opposite paths, and in which the piston rods are interconnected by means of a rocker arm lever, connected to the axis of the registration valve, or another equivalent, that against the entrance and exit of the concrete from the pumping group, said hydraulic cylinders being respectively equipped with a light in the vicinity of each of its ends, of which the first lights, arranged at one end of the cylinders, they communicate with each other through a duct, while the second lights are They are respectively connected by a tube to the two lights arranged on one side of the solenoid switch to leather lights, whose other two lights, placed on the opposite side, are connected to the oil pump and to an oil return duct, being equipped said hydraulic cylinders for oil distribution of a third light, respectively, arranged in an intermediate ventilation position with said first and second lights, said third lights being connected to each of the loading and unloading lights of one of the two hammers , while the interconnection duct of the first lights of said hydraulic cylinders have a tube that is derived from them and that leads directly to the tank.
