DEFINITION

Classification: 123/90.64

(under subclass 90.61) Device wherein the rod element is subjected to tension while performing its operational function.

(1) Note. This characteristic is in contrast with the arrangement found with most rod elements, which are of the "push" type and therefore function in compression. In a few instances the pull-type rod directly engages the valve, thereby eliminating the rocker element.
