Mechanism for driving a member in a reciprocating movement of variable stroke.

摘要

The invention relates to a mechanism for driving a member 1 in a reciprocating movement of adjustable amplitude consisting of a mobile assembly 14, 19 harnessed to the member 1 so as to convert the circular movement of a motor member 11 into a rectilinear movement characterised in that the mobile assembly 14 is permanently subjected to the action of an elastic member 25 which tends to place it in its end of working stroke position. Application to the driving of pumps of adjustable output. IMAGE
