Abstract: A windshield washer system has a nozzle mounted on a vehicle for issuing wash fluid to a windshield and a check valve for a fluid circuit from a supply of wash fluid to the nozzle. The nozzle has a fluid feed tube (50) integrally formed therewith with annular walls defining a washer fluid flow path and a diameter of at least D. The feed tube (50) has an external surface (55) adapted to receive and retain a flexible hose (60) from a supply of wash fluid. A spring shoulder (5') receives a coil compression spring (26') having upstream and downstream ends with the downstream end bearing on the spring shoulder (5'). A valve element (28') bears on the upstream end of the spring element (26'), and a tubular insert (54) having an inner end and an external diameter at least D and sufficient to form an elongated wash fluid seal (56) with the annular walls defining a washer fluid flow path, and complementary-shaped valve seat (53) formed on the inner end.
