ABSTRACT:
A valve includes a one-piece plastic body, and a plunger assembly inserted into the body from one end. The body includes a central cylindrical portion extending along a first axis, a tubular outlet portion extending along a second axis parallel to and offset from the first, so as to intersect the central portion only over a portion of the length of each, and a tubular inlet extending along a third axis perpendicular to the first axis and above the intersected portion thereof. An uninterruped 360.degree. band forming a seat remains between the outlet and the inlet. The plunger assembly includes a resilient, circumferential lip that engages the seat in the closed position of the valve, and a circumferential recess adjacent the lip, that permits fluid to flow through the valve in the open position.
