ABSTRACT:
An improved thermal expansion compensation manifold support is disclosed. The support includes a spring having a barrel and a skirt extending from the barrel, the skirt forming a recess. The spring has a first shoulder extending into the recess, and an end opposite the barrel. The support also includes a block having opposite ends, a finger portion formed at one end and a second shoulder formed at the opposite end. The finger has an end opposite the second shoulder, with the finger being dimensioned and configured to be inserted into the skirt's recess. The skirt and the block are dimensioned and configured such that when the finger is inserted into the recess, the skirt end abuts against the second shoulder and the finger end is separated from the first shoulder by a gap. The spring is made of a resilient metal and the skirt is dimensioned and configured such that the skirt forms a resilient spring allowing the support to be movable between a first position wherein the end of the finger is separated from the first shoulder by the gap, and a second position wherein the finger end abuts the first shoulder. The spring biases the support towards its first position.
