Abstract
A dispenser has a seal disk (), a valve member (), a plunger guide block (), a motor (), which rotates a cam-follower guide block (), and an end cam (). The seal disk () has communication holes (), () and a sliding surface (). The valve member has a sliding surface (), three plunger holes () and three plungers () inserted in the plunger holes. The cam-follower guide block () has three guide holes () that receive cam followers, which each have a body () with a ball () within a recess (). The ball () contacts the cam surface (A) of the cam () which causes the cam followers and plungers () to move back and forth parallel to the dispenser axis. The coefficient of friction between the ball and the recess is less than that between the ball and the cam surface (A).
