Abstract
The drive mechanism for imparting reciprocating movement to the tool plunger includes first and second drive members. The first drive member is mounted on an eccentric formation which is in turn mounted on a drive shaft thereby to impart a wobbling movement to the first drive member. The second drive member is in the form of a piston mounted for reciprocating movement within a bore formed in the first drive member. The second drive member is pivotally connected to the plunger. The second drive member has a helical groove in its exterior surface. A lubricant is forced along the groove in part due to the reciprocating movement of the second drive member in the bore of the first drive member.
