Title:
FLUID CYLINDER
Document Type and Number:
WIPO Patent Application WO/2019/146040
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fluid cylinder in which stroking while rotating with high precision is possible while particularly reducing power consumption and achieving a compact size. This fluid cylinder (1) has a cylinder body (2) and a shaft member (3) supported inside the cylinder body (2), the fluid cylinder characterized in that stroking in the axial direction is possible while the shaft member is rotated due to the action of a fluid. A rotation driving part (10), which causes the shaft member to rotate on the basis of the rotary pressure from the fluid, and a stroke driving part (11), which causes the shaft member to stroke on the basis of a cylinder control pressure from the fluid, are provided apart from each other inside the cylinder body.
