Title:
FIXED VOLUME DELIVERY DEVICE
Document Type and Number:
Japanese Patent JP2009250149
Kind Code:
A
Abstract:

To provide a delivery device superior in interlocking performance between the reciprocating operation of a piston and the rotary operation of the piston, and superior in quantitativeness.

This fixed volume delivery device 10 is provided for delivering liquid in a cylinder chamber 40R from a delivery port 43b formed at a pipe wall by sucking the liquid in the cylinder chamber 40R from a suction port 43s formed at the pipe wall of a cylinder 40 by reciprocating the piston 50 fitted to and inserted into the cylinder chamber 40R between the top dead center and the bottom dead center in the pipe axis C40 direction. The suction port 43s and the delivery port 43b are formed in mutually different positions in the peripheral direction of the cylinder 40. The piston 50 is formed with a flow passage 52 communicating with the cylinder chamber 40R. The piston 50 is moved to the top dead center or the bottom dead center in the pipe axis C40 direction by operation for rotating the piston 50 around the pipe axis C40 of the cylinder 40 so that the flow passage 52 communicates with the suction port 43s or the delivery port 43b.
