<p>A small envelope is achieved for an inelastically deformed connection between a spring cover (22) and a central housing in a spring brake actuator. The connection is deformed radially inwardly (32) and then extends radially outwardly (31) from the radially inwardly extending portion. This eliminates the radially outwardly extending portion and flanges as are typically utilized in the prior art. Thus, a much smaller enveloppe is provided. In preferred embodiments of this invention, a seal groove (36) is positioned axially adjacent a securement groove in the central housing. A seal (34) is positioned in the seal groove to ensure an air-tight seal. In addition, a unique diaphragm guiding structure (62) is incorporated into one embodiment of this invention.</p> |
