The housing of a pump, compressor, heat exchanger or another part which is subjected to thermally and/or otherwise induced expansion and contraction has several spaced-apart legs or analogous portions movably secured to a base plate or the like so that the legs are movable along straight or arcuate paths intersecting each other at or close to a fixed reference point within or without the confines of the part. The base plate has discrete guides for the legs of the expandible and contractible part, and such guides are designed to allow the respective portions to move along the corresponding paths toward or away from the reference point, depending upon whether the part contracts or expands. The guides can be slotted or recessed, or they may constitute rotary components having eccentric sections extending into openings of the respective legs. |
