Title:
PNEUMATIC ACTUATOR AND TURBOCHARGER
Document Type and Number:
WIPO Patent Application WO/2018/198166
Kind Code:
A1
Abstract:
In the present invention, due to rotation of a spindle (8), one end of a spindle main body (31) and the floor surface section of a recess (21) slide, the outer peripheral portion of a spring seat (9) and the inner wall portion of the recess (21) slide, and the spring seat (9) rises and falls along the axial direction of a rod (6). Due to the rising and falling of the spring seat (9), the attachment length of a spring (12) is adjusted, thereby adjusting the load of the spring (12). At this time, the polygonal spring seat (9) is in contact with the polygonal recess (21), so rotation of the spring seat (9) is restricted. Consequently, rotation of the spring (12) can be prevented, and a change in the pressure stroke characteristic and the hysteresis due to that rotation can be prevented.
