Abstract
A hydraulic press including a cylinder barrel, a piston and a seal housing. The cylinder barrel has an inner peripheral surface. The piston has a pressure side surface and is inserted in the cylinder barrel to form a chamber between the pressure side surface of the piston and the inner peripheral surface of the cylinder barrel. The chamber is configured to contain a hydraulic fluid. The seal housing includes an outer peripheral surface and an inner space which has an inner peripheral wall and which is configured to contain the hydraulic fluid. The seal housing is provided on the pressure side surface of the piston such that the outer peripheral surface is in contact with the inner peripheral surface of the cylinder barrel and such that the hydraulic fluid in the inner space presses the seal housing against the inner peripheral surface.
