Abstract
A buffering mechanism comprises a block member which is installed detachably in an actuator body, a piston which compresses air in a compressing chamber when a movable element abuts against the piston, and a check valve and a variable throttle valve which are provided in a passage for communication between the compressing chamber and the outside of the actuator body and which adjust a flow rate of the air discharged to the outside.
Claims10
A buffering mechanism for absorbing shocks applied to a movable element of an actuator when said movable element arrives at a displacement end position, said buffering mechanism comprising:
- a block member which is installed detachably in an actuator body;
- a displacement member which is provided in said block member displaceably in a displacement direction of said movable element and which compresses air in a compressing chamber in said block member when said movable element abuts against said displacement member;
- and
- a discharge flow rate-adjusting member which is provided in a passage for communication between said compressing chamber and the outside of said actuator body and which adjusts a flow rate of said air discharged to the outside.
