摘要

PROBLEM TO BE SOLVED: To provide a method for assembling a pump member and a piston pump structure enabling assembly of a piston under a condition where a piston pump is assembled on a base body.;SOLUTION: This method is provided with a plunger pushing and expanding process pushing and expanding plungers 123, 123 of a pair of piston pumps 120, 120 projecting into the bearing hoe 6 by inserting a jig 500 in a bearing hole 116 with using a space of liquid pocket part 117 and a motor insertion process pulling out the jig 500 from the bearing hole 16 and inserting an eccentric cam 211 into the bearing hole 116 after moving a motor 200 to a position where a side surface of the eccentric cam 211 butts on a tip surface of each plunger 123 under a condition where the plungers 123, 123 are pushed and expanded.;COPYRIGHT: (C)2009,JPO&INPIT
