Abstract
A pump for a printing press includes a plunger within a cylinder to be rotatable and reciprocatable and having a cutaway portion at its distal end, and a constant-speed motor for rotating and reciprocating the plunger. The plunger and the output shaft of the motor are radially offset relative to each other and inclined with respect to each other. The output shaft of the motor is coupled to the plunger via a transmission mechanism which includes an arm and a connection member. The arm is connected to, for example, the plunger, and the connection member is connected to, for example, the output shaft of the motor. The arm and the connection member are connected with each other at an eccentric position in such a manner that the arm and the connection member can displace relative to each other in the radial direction and can change the intersecting angle therebetween.
