Title:
FLUID PRESSURE CYLINDER
Document Type and Number:
Japanese Patent JP3118044
Kind Code:
B2
Abstract:
PURPOSE: To supply and discharge operation oil without direct connection of flexible pipe material such as a rubber hose to a cylinder main body even in case that a piston is a double acting type, allow oscillations of the cylinder main body, and prevent deterioration of durability in a fluid pressure cylinder which is oscillated when a driven member is operated.
CONSTITUTION: Operation oil flow passages 17c, 19c, 20c, 20d, 20e, 20f, 28, 32c, 33c, 33b, 33d which always communicate a pipeline port 32b on a support member 2 with a piston chamber 11 of a cylinder main body 10 are formed inside the cylinder main body 10 and the support member 2 which oscillatably supports the cylinder main body 10, in an oscillation range of the cylinder main body 10 in respect to the support member 2.
