Abstract
A valve assembly is described herein. The valve assembly has a housing having first and second body portions cooperating to enclose a cavity. The first body portion includes a cap having a nozzle that extends from the cap, and the nozzle defines an outlet. The first body portion includes a seat defining an orifice in fluid communication with the outlet and the cavity. A float is disposed inside the cavity. A seal is spaced from the seat when the float is in the initial position and the seal engages the seat when the float is in the displaced position.
Claims14
A valve assembly comprising:
- a housing including a first body portion and a second body portion attached to the first body portion, with the first body portion and the second body portion cooperating to enclose a cavity,
- wherein the first body portion includes a cap having a nozzle extending from the cap, and the nozzle defines an outlet, wherein the first body portion includes a seat defining an orifice in fluid communication with the outlet and the cavity, wherein the first body portion includes a column disposed inside the cavity so that the column defines a pocket open to the cavity, and wherein the second body portion includes a post;
- a float disposed inside the cavity and movable between an initial position and a displaced position;
- and
- a seal configured so that the seal is spaced from the seat when the float is in the initial position and the seal engages the seat when the float is in the displaced position, wherein the seal includes a first end defining a hole and a second end secured to the float, and
- wherein the post of the second body portion is disposed through the hole of the first end of the seal and into the pocket to secure the first end of the seal to the housing.
