Abstract:
An omnidirectional female valve for spraying viscous materials, which valve comprises:a valve body having a thickened top rim, a lower end having an intake opening, an upper end having a cup-shaped opening, an internal passageway extending from the lower end to the cup-shaped opening, an internal shoulder, and an external shoulder; a valve plunger slidably mounted in the cup-shaped opening of the valve body, which plunger contains an open cup having an upper surface for holding a lower end of an actuator, a closed bottom which fits inside a compression spring, and a lower shoulder; a compression spring having an upper end which abuts with the lower shoulder of the valve plunger and a lower end which abuts with the internal shoulder of the valve body; and an omnidirectional valve attachment comprising: an external top surface which abuts with the external shoulder of the valve body; side walls having interior surfaces and exterior surfaces; a hollow lower stem having a passageway through which viscous material passes when the valve is in an upright position; a lateral passageway through which the viscous material passes when the valve is in an upright or inverted position, which lateral passageway connects the passageway of the hollow lower stem and the internal passageway of the valve body; and a check valve container containing a constricted open end joining the lateral passageway, an external top surface, an internal top surface, a lateral opening through which the viscous material passes when the valve is in an inverted position, and a check ball which abuts with the constricted open end when the valve is in an upright position and with the internal top surface when the valve is in an inverted position.
