ABSTRACT:
A tank oil drain device comprises a drain receptacle associated with the tank, the receptacle defining a bore having a mouth opening to the tank exterior, the receptacle having a first port communicating between the tank interior and the bore; a plunger received in the bore, and a spring urging the plunger toward a position in the bore in which the first port is blocked; a seal normally sealing off between the bore and the side of the plunger at a location between the first port and the mouth; and lock structure carried by the receptacle, near the mouth, for retaining a tubular drain plug pushed into the bore for displacing the plunger in the bore sufficiently to unblock the first port thereby establishing oil draining communication via the first port and the plug to the exterior. The first port remains blocked by the plunger while the seal engages and seals off about the drain plug through a predetermined range of movement of the drain plug in the bore. Also, a shoulder on the receptacle is in axially spaced relation to the first port and the seal for seating the plunger in the bore in the initial position in which the plunger blocks the first port.
