Title:
AUTOMATICALLY CENTERING-TYPE DRAIN VALVE
Document Type and Number:
Japanese Patent JP3477459
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a drain valve used in co-operation with a fuel filter having a water separating function.
SOLUTION: This drain valve 20 includes a control lever 21 loaded by a spring co-operating with a flow control piston 22 for rotating the piston from a normally-closed state of the drain valve to an opened state of the drain valve. In the normally-closed state, the piston 22 is rotated to allow a first spherical part 32 to close the flow communication between a drainage channel and a water channel. Simultaneously, a second spherical part 33 closes the flow communication between an airflow channel 36 and a ventilation channel 42. In the opened state, the drainage channel 41 and the water channel 35 are communicated, and the airflow channel 36 and the ventilation channel 42 are communicated to discharge the water from the fuel filter, and to introduce the air into the fuel filter.
