<p>A service brake actuator (10) having a housing base (20) having a center portion (38) and a housing cover (22) having a center portion (44) is provided. The center portion (38) of the housing base (20) and the center portion (44) of the housing cover (22) telescopingly fit together in an assembled position and define an annular space therebetween. A diaphragm (30) having a thickness greater than the thickness of the annular space between the center portion (38) of the housing base (20) and the center portion (44) of the housing cover (22) is held in the annular space by radial forces generated by compression of the diaphragm (30) in the annular space. It should be understood that the magnitude of the radial forces holding the diaphragm (30) in the annular space is variable depending on the thickness of the annular space.</p> |
