Title:
FLUID PRESSURE CYLINDER
Document Type and Number:
WIPO Patent Application WO/2020/054668
Kind Code:
A1
Abstract:
When viewed in section, a cylinder hole (14) in a fluid pressure cylinder (10) has a polygonal shape including inner circumferential surfaces parallel to a plurality of surfaces constituting a body (12). A piston (30) has a polygonal outer edge having a shape corresponding to the shape of the cylinder hole (14) and partitions the cylinder hole (14) into a head-side cylinder chamber (46) and a rod-side cylinder chamber (48). The body (12) is cut off so that a first side surface (20) has a stepped shape, and a solenoid valve (130) is disposed in a solenoid valve arrangement space (74) formed by cutting off the body. The solenoid valve (130) is disposed inside a virtual outer shape (122) defined by most-protruding faces in the respective surfaces.
