Title:
GEAR PUMP OR MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/073602
Kind Code:
A1
Abstract:
Provided is a gear pump or a motor provided with: a casing internally provided with a gear housing compartment in which a pair of gears are housed; a side plate interposed between the casing and the gears; and a gasket which is disposed on a non-slide surface which is a surface on the opposite side of a slide surface of the side plate facing the gears, and which divides a space between the non-slide surface and the casing into a higher pressure side and a lower pressure side. The gear pump or a motor is configured such that, in order to discover early the mounting of the side plate in a wrong attitude, such as the upper and lower sides thereof being reversed or the higher pressure portion side and the lower pressure portion side being reversed, flow rate efficiency is decreased when the side plate is in an attitude other than a predetermined attitude, compared to when the side plate is in the predetermined attitude.
