VARYING CAPACITY PUMPING UNIT
The invention relates to a varying capacity pumping unit meant for extracting oil, liquids, etc. According to the invention, the varying capacity pumping unit ensures flow regulation in oil production by providing some double articulated rods (9) with some spherical bearings (10) taking over the motion thereof and converting it in oscillatory motion which is further transmitted to some triangle-shaped members (11). Said triangle-shaped members (11) are stiffened to each other by means of a stiffening part (12) and some bearings (13) of a walking beam (14) performing the alternating rotation motion under a variable rotation angle, said rotation motion being determined by some double cranks (21) articulated to the triangle-shaped members (11) by means of some bearings (22) and to some sliders (24) by some bearings (23).
