Title:
小型の倍力空気圧式作動装置
Document Type and Number:
Japanese Patent JP2013510274
Kind Code:
A
Abstract:
A compact force multiplying actuator 10 and its associated valve 20 are disclosed. The actuator 10 and valve 20 include piston heads 31 and 32 and force multiplying load beams 52 and 53. Belleville springs 81 and 82 are disposed axially between the piston heads 31, 32 and the load beams 52, 53. The Belleville springs 81 and 82 act through an output member 71 to retain a valve member 88 in a closed position. When pneumatic pressure is applied against the piston heads 31 and 32, movement of the piston heads 31 and 32 is transferred through a force transfer member 45 and through the force multiplying load beams 52 and 53 to move the output member 71 against the bias of the Belleville springs 81 and 82 to allow the valve member 88 to open.
