|1. (WO2018037876) SLIDE VALVE AND REFRIGERATION CYCLE SYSTEM|
|Applicants:||SAGINOMIYA SEISAKUSHO, INC.
|Title:||SLIDE VALVE AND REFRIGERATION CYCLE SYSTEM|
Provided is a slide valve wherein a stopper function on pistons (3) is stabilized and variance in operating performance is reduced. The ends of a cylindrical section (101) of a valve housing (10) are sealed off with stopper bodies (1). Width expansion sections (12) are provided to the inner side of fitting sections (11) of the stopper bodies (1) that are fitted to the interior of the cylindrical section (101). Expanded stopper surfaces (12a) of the width expansion sections (12) are flush with stopper plate (32)-side (piston (3)-side) end surfaces (11a) of the fitting sections (11). Stopper plates (32) of the pistons (3) are abutted against the expanded stopper surfaces (12a), along with the end surfaces (11a). Due to this configuration, the portions of contact with the stopper plates (32) are widened only by an amount commensurate with the expanded stopper surfaces (12a). A difference in contact surface area between a portion of the contact portions that has the maximum width and a portion that has the minimum width is reduced, and the stopper function is stabilized.
