Abstract
An anti-drain valve for a plate cooler has a plastic housing having a generally cylindrical outer wall with open ends, and an inner support structure integrally formed therewith, and with a valve seat. A piston is located within the support structure and axially movable toward and away from the valve seat. A biasing member biases the piston toward the valve seat. A resilient sealing element provides a seal between the housing and the base plate. The outer wall has first and second portions, the first portion including a plurality of inwardly bendable detents defined by slots through the outer wall for attaching the valve to the base plate of the plate cooler.
Claims19
An anti-drain valve for a plate cooler having a base plate with an oil opening, the anti-drain valve comprising:
- (a) aplastic housing having a generally cylindrical outer wall with an inner surface and an outer surface, open first and second ends, and an inner support structure integrally formed with the outer wall and attached to the inner surface thereof;
- (b) a valve seat proximate to the second end of the housing;
- (c) a piston located within the support structure and axially movable toward and away from the valve seat;
- (d) a biasing member located within the support structure and biasing the piston toward the valve seat;
- and
- (e) a first resilient sealing element between the housing and the base plate;
- wherein the outer wall of the housing comprises a first portion and an adjacent second portion, the first portion being proximate to the first end of the housing and defining a first axial surface having a first outside diameter which is smaller than an inside diameter of the oil opening of the base plate, and the second portion being distal to the first end of the housing and defining a second axial surface having a second outside diameter which is larger than the inside diameter of the oil opening;
- wherein the first portion of the housing further defines a plurality of inwardly bendable detents, each of the detents being defined by a pair of slots through the outer wall and proximate to the first end of the housing;
- and
- wherein each of the detents has a tip projecting radially outwardly from the first axial surface.
