The vacuum pump (12) is operated by a rod (26) with a to-and-fro rectilinear movement, and the engine (14) is equipped with a crankshaft (16) mounted so it can rotate inside a block (18) of the engine. In this arrangement, the vacuum pump (12) is fixed to the block (18), the free end (47) of the operating rod (26) being operated by a turning cam (44) integral with the crankshaft (16). <IMAGE>
