Title:
CYLINDER DEVICE
Document Type and Number:
Japanese Patent JPH0246302
Kind Code:
A
Abstract:

PURPOSE: To achieve sufficient acceleration and pressure intensification by moving two pistons forward and backward as driving sources, and by transferring the movement of the piston to a third piston via the fluid filled in an operating oil chamber.

CONSTITUTION: A motor 1 is connected to a second and first pistons 30, 40, via deceleration gears 10 to 13, a ball spring 20, and a ball nut 21, and a first, second, and third operating oil chambers A through C are formed between the second and first pistons 30, 40 and the third piston 50, and the operating oil chambers A through C are filled with fluid. Since the movement of the second and first pistons 30, 40 can be transferred to the third piston 50 via the filled fluid, acceleration and pressure intensifications are possible.
