Abstract

PURPOSE: To increase a strength of a stopper and prevent a shuttoff of an oil passageway due to a damage of the stopper by a method wherein the stopper, rotatable with a valve rod integrally and at least a tip portion thereof is visible from outside, is provided at a portion of the valve rod located above an oil tank.
CONSTITUTION: An oil switching valve 3 is equipped on an oil tank 1 for a hydraulic device and two sets of oil coolers are used alternately by switching oil passageways without shutting off a flow of the oil. A cock 3 located in the oil tank 1 and a switching handle 12 located above the oil tank 1 are connected by a valve rod 7. A stopper 32 rotated integrally with the valve rod 7 is provided at a portion of the valve rod 7 located above the oil tank 1. A rotating range regulating body 24a for the stopper 32 is provided on a valve rod cover 8a, 8b fixed to an upper surface of the oil tank 1. The stopper 32 is constituted so that at least a tip portion thereof is visible from outside.
