Abstract
A preloaded spring assembly is disclosed having a compression coil spring received interior of a housing. The housing is made of opposed cup-shaped housing members having open ends with one of the cup-shaped members having a smaller diameter and having its open end projecting into the open end of the second housing member. The respective open ends are configured to provide a lock abutment preventing separation of the housing members beyond a certain dimension whereby the spring positioned interior of the housing members having its opposite ends in contact with the bottoms of the respective cup-shaped housing members is provided with a compressive preload. Also, disclosed is a method of manufacturing the preloaded spring assembly which configures the open ends to provide a mechanical interlock during assembly such that the spring is preloaded at the time of assembly.
