WIPO Patent Application WO/2013/031972

Kind Code:

A1

Abstract:

[Problem] The present invention relates to a new pump unit which is capable of preventing an impact and vibration which are generated when a pump for discharging (filling) a capsule liquid is in operation at a high speed while manufacturing a capsule by coating the capsule liquid with an outer coating part, expanding a length of time of capsule liquid discharge and an actual fillable area, and controlling a discharge pressure which may increase during a high-speed rotation. [Solution] According to the pump unit of the present invention, an end of a plunger pin is extended to protrude out of a pump chamber, and receives driving by a shifter at the protruding portion for a reciprocating movement in the pump chamber. The shifter comprises a rotating pendulum lever, and the plunger pin reciprocates in the pump chamber due to a reciprocating rotation of the pendulum lever.
