摘要： In a pump (P) intermittently rotated and controlled by a motor (4), the motor rise in temperature and ink supply is unstable when an operation of the pump is stopped in a magnetizing state.
Therefore, the invention resides in a pump (P) for a printing machine characterized in that the pump has a base (1); a cylinder (2) having a suction hole (21,11) and a discharge hole (22,12) opened in positions different from each other in phase on the inner circumferential face of a main hole (20); a plunger (3) fitted to an opening side of the main hole (20) of the cylinder (2) so as to be axially moved and rotated from an end tip of the main hole (20) and closing the suction hole (21,11) or/and the discharge hole (22,12); a motor (4) attached to the base (1) such that a rotating central line (CL1) of a rotating shaft (40) crosses that (CL2) of the plunger (3) at a predetermined crossing angle θ; a transmission mechanism (6) constructed by an arm (60) and a connection member (61); and retrogression preventing means (5,5a,5b,5c) for arranging the plunger (3) temporarily stopped at a discharging stroke during an operation of the pump (P) intermittently operated by the motor (4) such that no plunger (3) is retreated and angularly displaced in a direction reverse to a predetermined operating direction.
