Document Type and Number:
WIPO Patent Application WO/1995/011193
Kind Code:
A1
Abstract:
This invention relates to an oil supply apparatus for oil tank trucks, which utilizes an air separator of an air separating hose formed by an angularly bent portion of a feed hose adapted to separate air from an oil during an oil supplying operation, or an air separator of an air separating tank in which an upper oil detecting sensor is provided, and which is capable of supplying an accurate amount of oil. An oil supply apparatus for oil tank trucks, characterized in that an oil tank (23) at a front end and an oil gauge (7) at a rear end are provided in a hydraulic pump (11) via an air separator (21), which hydraulic pump (11) utilizes an electronic clutch by sending an oil (petroleum or light oil) from the oil tank (23) with compressed water, the air separator (21) comprising a petroleum separating valve (16), a solenoid petroleum valve (16), a light oil separating valve (17) and a solenoid light oil valve (15), an air separating hose (4) the diameter of which is smaller than that of a one-end-closed feed hose (1b) being connected so that the hose (4) is bent angularly at an intermediate portion thereof, the air in an oil which is being supplied being separated.
