摘要： The invention relates to a locking arrangement for a key member used in a brake booster. A key member includes an arcuate portion which surrounds substantially one-half the perimeter of a valve body, and engaging recesses are formed at the opposite ends of the arcuate portion on the inner side. A retainer surrounds substantially one-half the perimeter of the valve body at a location opposite to the arcuate portion of the key member. The opposite ends of the retainer are formed with engaging pawls on the outer side for engaging with the engaging recesses under the resilience of the retainer. Accordingly, by merely assembling the key member and the retainer with the valve body, the engaging pawls of the retainer can be automatically engaged with the engaging recesses in the key member, thereby preventing the withdrawal of the retainer and the key member from the valve body.

摘要： A vacuum power servo booster having an improved retainer for an annular seat of a control valve body. A spring seat for a compression spring which presses the annular seat against the valve housing is formed at the front end portion of a retainer. A recess is formed on the front side of the spring seat to receive the skirt of the control valve body. The spring seat is formed by bending a smaller diameter portion of the retainer inwardly prior to assembly. In this manner, the longitudinal axis of the retainer is made to substantially coincide with that of the control valve body.
