ク調整装置。[Claims for Utility Model Registration] (1) A stroke adjustment device for a reciprocating pump that obtains rotational driving force from a rotational driving means and transmits reciprocating motion with a variable stroke to a pump section via a connecting member to perform pump operation. a first eccentric cam member connected to the connecting member via an eccentric shaft on the front side; a second eccentric cam member fitted to the first eccentric cam member so as to be relatively rotatable; a mounting member attached to the rotational drive means; a fixing means for removably fixing the mounting member and the second eccentric cam member and operable from the front side; and the first and second eccentric cam members. an engaging tooth portion formed on a corresponding contact surface along the radial direction of the second eccentric cam member, and by fixing the second eccentric cam member to the mounting member by the fixing means,
A stroke adjustment device for a reciprocating pump, characterized in that the engaging tooth portions of the eccentric cam members are engaged with each other, and both eccentric cam members are fixed at any adjustment rotational position. (2) A utility model registration request in which the eccentric shaft is integrally fixed to the first eccentric cam member, and the front end of the eccentric shaft is configured as an operating section for rotating the first eccentric cam member. A stroke adjustment device for a reciprocating pump according to item 1. (3) The stroke adjusting device for a reciprocating pump as set forth in claim 1 or 2, wherein a scale indicating the stroke amount is provided on the front side of both eccentric cam members.
