(under the class definition) Apparatus comprising a working member and a power transmission member movable with respect thereto, a resilient device interposed between and in engagement with said members, said members being so related that movement of one of said members is effective to move said other member by means of said resilient element.
(1) Note. A mere resilient piston side wall portion which forms a seal means for the piston positioned between an end face portion and a second piston portion such that movement of said end face portion toward said second portion effects radial movement of said resilient portion is excluded from this definition. Such subject matter is classified below on other features.

130+, and the search there noted, for a separate biasing means for a working member.
193+, for a resilient piston side wall portion interposed between a piston end face portion and a relatively axially movable other portion, and spring means for biasing said end face portion and other portion toward each other to effect radial movement of the resilient side wall portion.
205+, for a resilient piston side wall portion interposed between an end face portion and another piston portion in which relative axial adjustment of said end face portion and other portion effects radial movement of the resilient side wall portion. 247, for a resilient piston side wall portion interposed between an end face portion and another relatively axially movable other piston portion in which fluid pressure responsive axial movement of the end face portion effects radial movement of the resilient side wall portion.
