Claims

[Claims for Utility Model Registration] 1 A main body block is provided with a pair of cylinders on both sides, and pistons reciprocating within these cylinders are connected to each other by a rod that passes through the main body block in an airtight manner, Therefore, the interior of both cylinders is divided into a pressure increase chamber and a drive chamber, and pressure fluid is alternately supplied to the drive chambers of the pair of cylinders using a switching valve provided in the main body block to cause the pistons to reciprocate and increase the pressure. In a fluid pressure booster that outputs fluid in a pressure chamber under increased pressure, the cylinder is configured by attaching a first side cover to the outer end of a tube whose one end is fitted into the main body block, and the first side cover Attach one end of the tube of the continuous cylinder, attach a second side cover to the outer end of the tube, and connect a piston rod defining two drive chambers in the tube to the piston rod, Each tube, each side cover, and each piston have the same structure and are made into common parts, and each side cover is provided with a through hole for guiding the fluid pressure supplied and discharged from the switching valve to each drive chamber. Fluid pressure booster. 2 A pair of cylinders are provided on both sides of the main body block, and pistons reciprocating within these cylinders are connected to each other by a rod that passes through the main body block in an airtight manner. It is divided into a pressure chamber and a drive chamber, and a switching valve installed in the main body block alternately supplies pressure fluid to the drive chambers of the pair of cylinders, causing the pistons to reciprocate, and increasing the pressure of the fluid in the pressure increase chamber. In the fluid pressure booster, the cylinder is constructed by attaching a first side cover to the outer end of a tube whose one end is fitted into the main body block, and the side cover is a common part with the tube of the cylinder. The piston rod in the cylinder can be connected to the piston rod in the continuous cylinder through a side cover, and the side cover is provided with a valve for supplying and discharging the piston from the switching valve to each drive chamber. 1. A fluid pressure increase device characterized by having a through hole for guiding fluid pressure.
