    A pressure transformer including at least three driving pistons coupled to driven plungersby means of piston rods; to ensure a fixed staggered position of the piston rods during the entire operation of the transformer, a tubular shaft supporting an inclined wobble disk is arranged for rotation in the driving part between respective piston rods; a peripheral groove on the wobble disk engages pushing rollers mounted for rotation on respective piston rods and additional rollers are mounted on the opposite side of the piston rods to engage a straight guiding groove in the housing of the driving part to secure the piston rods against rotation about their axes.

    The invention relates to hydraulic machine building, namely to hydraulic pressure transducers. Prepressure pressure is known, containing at least three parallel inlet pumps. Cylinder with pistons, having suction and pressure valves, through which the cavities of the injection cylinders communicate respectively with the suction and pressure tanks of the pumped medium and at least three parallelly arranged hydro4 drive cylinders, the pistons of which are connected by rods to the pistons of the discharge qi cylinders, the rods are kinematically connected with each other by means of rollers and an inclined washer mounted on a synchronizing shaft located parallel to the axes of the cylinders, and the hydraulic actuators communicate with the source of drive fluid and with the drain through the control valve 11. The disadvantage of this converter is the complexity of the distribution node. The aim of the invention is to simplify the design and increase reliability. This goal is achieved by the fact that in a pressure transducer containing at least three parallelly arranged discharge cylinders with pistons, having suction and pressure valves, through which the cavities of the discharge cylinders correspond with suction and discharge tanks PG: flowable medium and at least three in parallel are located hydraulically driven cylinders, the pistons of which are connected to the pistons of the injection cylinders, the rods being kinematically connected with each other by means of rollers and an inclined shaft The cylinders are connected to a synchronizing shaft located parallel to the axes of the cylinders, and the hydraulic cylinders communicate with a source of driving fluid and with a drain through the control spool, the synchronizing shaft is hollow, and the control distributor is executed in the form of a flat segment disk fixed to the synchronizing shaft and connected through its internal cavity with a source of driving fluid. Fig. 1 shows a pressure transducer, longitudinal section; Fig. 2 is a section A-A in Fig. D; Fig. 3 is a section B-B in Fig. 1. The pressure converter is provided with three injection cylinders 1 with pistons 2, having pressure valves 3 through which the cavities 4 of the injection cylinders 1 communicates with the pressure tank of the pumped medium, and three parallel hydraulic cylinders 5, the pistons 6 of which are connected by rods 7 to the pistons 2 of the discharge cylinders 1, and the rods 7 are connected by means of rollers 8 and an inclined washer 9 fixed to the synchronizing shaft 10 located parallel to the cylinder axis1 1 and 5, and the hydraulically driven cylinders 5 communicate with a source of driving fluid and with a drain through the control valve 11 connected through the internal cavity 12 of the synchronizing shaft 10 with a source of driving fluid through the connector 13, the drive fluid is fed to the control valve 11 through channels 14 and 15, and through the opening 16, fluid is supplied to the piston 6o. The pumped medium through the valve 3 and the channel 17 is injected to the tank of the pumped medium. The drive fluid through the nozzle 13 is fed into the internal cavity 12 of the synchronizing shaft 10 and flows through the channel 14 into the distribution channel 15 °. In the area of the distribution channel there is an opening 16 through which the piston 6 is loaded by the pressure of the driving liquid. The bore 16 is blocked by a spool 11 o. The piston 6 supplied to this bore reaches the bottom dead center. The third hole 16 is connected to a drain. Under the action of pressure, the piston 6 rises up, turning the inclined washer 9 by means of rollers 8 ,. at the same time, the pumped liquid is displaced from the injection cylinder 1 through valve 3, which channel 17 is connected to the tank of the pumped medium. The proposed design makes it possible to create a cheap and efficient design of the pressure transducer.
