Abstract

Disclosed is a four-in pump which includes: a gear box ( 21 ) being arranged between a first and a second cylinder blocks ( 100 and 200 ), a gearing means ( 1 ) arranged within the gearbox ( 21 ) being connected with a driving shaft ( 13 ) of a motor ( 11 ), four eccentric shafts ES 1 through ES 4 being mounted for possibly performing eccentric rotational motion, on the gearing means ( 1 ), respectively, four pistons ( 120, 160, 220, 260 ) respectively mounted on the eccentric shafts ES 1 through ES 4 being arranged on an upper and a lower volume chambers ( 110 and 150 ) of the first cylinder block ( 100 ) and on an upper and a lower volume chambers ( 210 and 250 ) of the second cylinder block ( 200 ), respectively.

Description

Technical field [0001] The present invention relates to a four-in pump, in which pistons respectively arranged in four volume chambers perform pumping motion, and more specifically to such a four-in pump, in which four eccentric shafts are arranged in The transmission device of the gear box between the first and second cylinders performs eccentric rotation, and the pistons respectively mounted on the eccentric shafts are inscribed in the volume chambers in the first and second cylinders at different speeds from each other. Eccentric circular motion. Background technique [0002] Patent Application No. 2001-77842 (filed on December 10, 2001) discloses "Volumetype pump having a pair of volume chambers and assembling method thereof". [0003] According to the above positive displacement pump, the diameter of the eccentric shaft can be made large enough to withstand the torsional stress, and the side of the piston is tightly attached to the inner wall of the cylinder, so that the pum...
