ANTIFRICTION ROLLER MEANS FOR PLUNGERS |
摘要 |
A plunger has a perimeter for spaced cooperation with a guide bore along a reciprocation axis. For alleviating lateral thrust friction between the plunger perimeter and guide bore, antifriction roller structure has an axle with journals engaged in radius bearings on axis transverse to the reciprocation axis of the plunger. Mounting of the antifriction roller structure is such that annular wheel surfaces on the roller effect rolling engagement with the guide bore.
