Title:
3-POSITION OPERATING ACTUATOR AND PERMANENT-MAGNET EDDY-CURRENT DECELERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/126087
Kind Code:
A1
Abstract:
The present invention achieves 3-position operation in one cylinder without using a spring. A partition plate (19) and an intermediate check plate (18) having a spacing as appropriate are affixed in the axial direction of a cylinder (11) of which both ends are closed by pressing lids (16, 17). Inserted movably in the axial direction of the cylinder are: a first piston (13) between pressing lid (16) and the intermediate check plate (18); a second piston (14) between the intermediate check plate (18) and the partition plate (19); and a third piston (15) between the partition plate (19) and pressing lid (17). A rod (12) that penetrates the partition plate (19), second piston (14), intermediate check plate (18), first piston (13), and pressing lid (16), and that has a tip that protrudes to the outside of the cylinder (11) is disposed movably in the axial direction of the cylinder, and the third piston (15) is disposed at the base of the rod (12). A stopper (22) that causes the motion of the first or second piston (13 or 14) is affixed to the middle portion of the rod (12).
