FLUID PRESSURE MACHINE.

摘要

A fluid pressure machine which has a fluid unit formed by connecting together a plurality of blocks having different functions, and which is suitable to be used as a vacuum generating unit connected to an external machine. This fluid pressure machine includes a plug-in type signal connector provided with a plurality of terminals concentrated in a wall of the fluid unit so as to electrically connect the blocks to an external machine, and a plug-in type fluid passage connector provided with terminals concentrated in the wall of the fluid unit so as to connect the blocks hydraulically to the external machine through tubular members to be inserted into the terminals.
