Output regulator applicable to metering pumps

摘要

The purpose is to produce a simple, reliable and economical output regulator (1), comprising a sprocket (14) keyed to a hollow shaft (16) rotating with respect to a main axis (A) parallel to the axis of rotation (C) of a crank (6). The inside of the hollow shaft (16) on opposite sides of the main axis (A) holds a sliding shaft (17) and a contoured shaft (18). The contoured shaft (18) has its own axis (B) parallel to the main axis (A). The sliding shaft (17) has a first extremity (19) coaxial with the main axis (A) and a second extremity (20) provided with a first (21) and a second (22) coupling which engage it while allowing it to slide parallel to the main axis (A), both on said hollow shaft (16) and on said contoured shaft (18). The contoured shaft (18) has a first section (23) provided with a helical projection (24) which is part of the second coupling (22) and a second section (25) keyed to the crank button (6) of the first kinematic mechanism (3). <IMAGE>
