Abstract
A valve assembly of non-metallic construction which requires no tools for disassembly and servicing. A plunger provided with longitudinal channels is activated by a double arm yoke which is acted upon by the float arm. Dual ports provide paired inlet streams directed away from the lever and float.
Claims27
A float valve for an animal watering tank, the invention comprising
- a housing having an inlet connectable to a pressurized water source,
- a valve seat mounted within said inlet,
- a plunger moveable supported in said housing for axial movement into and out of a seated position with said valve seat,
- a first lever member pivoted at one end on said housing to one side of said plunger for pivotal movement about an axis normal to the axis of said plunger from a first position in contact engagement with said plunger to a second position out of the path of axial movement of said plunger,
- a second lever member pivoted on said housing to the opposite side of said plunger for pivotal movement about an axis parallel to the axis of said first lever member,
- a first end of said second lever member being in overlying contact engagement with the free end of said first lever member, when the first lever member is in the first position therefor,
- said second lever member being pivotal out of engagement with said free end of said first lever member to a second position out of the path of axial movement of said plunger,
- said first lever member comprising a single element having a pair of arms pivotally secured at one end thereof to said valve housing,
- said arms being joined by a unitary transverse element,
- said transverse element having a radial extension depending therefrom,
- said extension of said first lever member comprising the free end of said first lever member that is in contact engagement with said second lever.

The claim of invention 1 wherein
- said transverse element engaging said plunger when said first lever member is in its first position.
Float valve apparatus for an animal watering tank, the invention comprising
- a valve housing having an inlet connectable to a source of liquid under pressure,
- a valve seat element mounted in said inlet of said valve housing,
- a plunger reciprocatingly fitted within said valve housing and selectively engaging said valve seat,
- a first lever pivotally mounted to said valve housing,
- said first lever interacting with said plunger when said first lever is in a first operating position for selectively urging said plunger in engagement with said valve seat,
- an actuating arm pivotally mounted to said valve housing and interacting with said first lever, when said first lever is in its first operating position,
- said actuating arm being sufficiently pivotable to allow said first lever to be pivoted to a second position therefor out of the way of the direction of travel of said plunger,
- said plunger being slideably removable from said housing when said first lever is pivoted to its second position out of the direction of movement of said plunger,
- said first lever comprises a single element having a pair of arms pivotally secured at one end thereof to said valve housing.
- said other end of said arms being joined by a unitary transverse element with a radial projection extending from said transverse element for interaction with said actuating arm.

A float valve for an animal waterer, the invention comprising
- a valve housing having an inlet connectable to a source of liquid under pressure,
- a valve seat element mounted in said inlet of said valve housing,
- a generally cylindrical body reciprocatingly fitted within said valve housing and selectively engaging said valve seat,
- a first lever pivotally mounted to said valve housing and interacting with said cylindrical body, when said first lever is in a first operating position,
- an actuating arm pivotally mounted to said valve housing and interacting with said first lever, when said first lever is in its first operating position,
- said first lever comprises a single element having a pair of spaced apart, arms joined by a unitary transverse element,
- each of said arms pivotally attached to said housing,
- said transverse element of said first lever engageable with said body,
- said first lever is provided with a projection depending from said transverse element thereof,
- said projection of said first lever engages said actuating arm, when said first lever is in its first operating position,
- said actuating arm being sufficiently pivotable to allow said first lever to be pivoted out of the locus of possible travel of said body,
- said body being slideably removable from said housing when said first lever is pivoted to its second position out of the locus of possible travel of said body,
- said body is provided with a plurality of axially extending channels upon the outer surface thereof.
