Title:
OIL FEEDER
Document Type and Number:
Japanese Patent JPH0710200
Kind Code:
A
Abstract:

PURPOSE: To prevent damage to a valve and outflow of oil even when oil in an oil feed nozzle expands due to temperature rise, by providing the part where the oil feed nozzle and an oil feed hose are connected with a check valve, and also providing one of them with a bypass.

CONSTITUTION: For example, when the feed of A-type oil in an oil storage tank 1 is finished, the A-type oil in an oil feed hose 9a and that in an oil feed nozzle 17 remain in them as it is because an electromagnetic valve 8a is provided in the part where a pipeline 5 and the oil feed hose 9a are connected. Even when temperature rises in this condition and the oil in the oil feed nozzle 17 expands and flows toward other oil-feed hoses 9a-9c from the connecting part of the oil feed nozzle 17, it is prevented from flowing into the oil-feed hoses 9a-9c because check valves 10a-10c are provided between the corresponding oil-feed hoses 9a-9c and the oil feed nozzle 17. The oil which has expanded in the oil feed nozzle 17 flows into a bypass passage 15, and further flows into the oil feed hose 9c by pushing and opening a relief valve 16 provided in the bypass passage 15.
