Abstract:
The boot (10) includes a ventilation passage (18) spaced from a bore (16) and which extends between two openings (52,54) in a body (14). A one-way valve (12) comprises two walls (56) which are connected on opposing sides of one of the openings and at an angle so that they form a duckbill shape. The walls engage each other and define a sealed space (66) above the opening and below the walls and a slit (68) formed between the walls. The walls normally remain in contact at the slit until a cracking pressure is reached where the walls begin to separate.
