ABSTRACT:
An improved fluid power motor construction provides for an encompassing guard tube or cylinder to be spaced around the entire cylindrical body section which accommodates the reciprocating piston member in order to preclude any harmful denting to such body section. The guard cylinder in the present improved constructions is also typically used to serve multiple structural functions, as for example, in one embodiment, it can be used to hold the end portions of the body section tightly to the end cap sections. In a tie rod type of fluid motor constructions, the guard tube will serve as a longitudinal spacer between the end portions of the unit, while with respect to a special repairable form of motor unit the outer guard tube will serve as the tying compression-tension member between the end sections.
