ABSTRACT:
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.
