Abstract

PURPOSE:To eliminate the sliding portion by partitioning a pump chamber into an intermediate chamber formed with a suction chamber, conducted to the suction port, ground packing and a disc and a delivery chamber conducted to the delivery port thereby moving the disc up and down together with the rod. CONSTITUTION:It is comprised of a body 1 having a suction port 4 and a delivery port 5 while containing two ground packing fittings 19, 20 and two conduction ports 33, 34, two rods 13, 14 reciprocating in the opposite direction in the body 1, ground packings 17, 18 the central portions of which are stopped with intervals to each rod and the discs 25, 26 where the ground packings 17, 18 and the discs 25, 26 are made of flexible material then the body 1 is partitioned into the crank chamber 2 and the pump chamber 3 while the outercircumference of each disc 25, 26 is resiliently contacted against the conduction port in the body 1 to partition the pump chamber into the suction chambers (a), (b), and (c).
