(under the class definition) Apparatus comprising a chamber associated with the expansible chamber device, said chamber being separate from that portion of the working chamber traversed by the working member and being in open communication therewith and forming a storage space for a noncompressible liquid type working fluid when said fluid is not in that portion of the working chamber traversed by said working member.
(1) Note. A mere pipe or conduit leading to the portion of the expansible chamber device traversed by the working member does not constitute a reservoir for this subclass. For classification in this subclass the device must include a container-like structure into which the working fluid is exhausted upon being expelled from the portion of the chamber traversed by the working member.
