ABSTRACT:
A linear braking mechanism for fluid actuators defined by a cylinder enclosing a cavity having a piston/piston rod assembly reciprocally mounted therein. The braking mechanism includes a spring biased body which is disposed for engaging and retarding the movement of the piston as it nears the end of its travel. A pressure equalizing metering port is provided in the body of the braking mechanism to equalize pressure on opposite sides of the spring biased body.
