INHALATION AND COMPRESSION PUMP DEVICE WHOSE ELLIPSE PISTON RECIPROCATES BETWEEN FOLLOWER PIECE AND COMPLEX CYLINDER GROOVE CAM WHILE FITTED IN ELLIPSE CYLINDER IN CYLINDER

摘要

PROBLEM TO BE SOLVED: To ensure a large amount of discharging in a small device, by linearly reciprocating a follower piece engaged with a complex cylinder groove cam provided on a middle part of a rotating shaft by rotation of the rotating shaft, and allowing an ellipse piston to reciprocate with the follower piece.;SOLUTION: This device comprises a complex cylinder groove cam 13 composed of double helical curve provided with grooves of a right kink and a left kink along the helical curve. The right kink and the left kink are superimposed at the same position, and a projecting portion and a flat portion are provided on position displaced by a half turn at both ends of each kink groove. A follower piece 14-1 is engaged with the complex cylinder groove cam 13, and made to reciprocate in a lateral direction by rotation of the cam 13. An ellipse piston 3-1 comprising the follower piece 14-1 at a middle part is reciprocated with the follower piece 14-1 in an ellipse cylinder 2, thereby discharging a fluid body taken from a suction valve 5-1 through a discharging valve 6-1 after increasing pressure thereof.;COPYRIGHT: (C)2000,JPO
