Abstract

A mechanical tappet with automatic take-up of slack comprises a first member (1) arranged to be kept in contact with the stem (10) of a valve (11), and a second member (2) mobile axially relative to the first and arranged to cooperate with the operating cam (17) of said valve, between said two members (1, 2) there being disposed a resilient element (5) arranged to move the first member axially relative to the second in order to constantly keep the first (1) in contact with said stem (10) and the second (2) in contact with said cam (17). The element (5) may be a spiral spring and the members (1, 2) may be held together by a screw thread of trapezoidal cross section. <IMAGE>
