Abstract
A drain valve to be used with numerous drain applications, such as draining fluid from an engine, includes in an exemplary embodiment a valve body, a first and second o-ring and a valve sleeve. The drain valve eliminates the need for a tool, such as a wrench, to drain the fluid from the engine, for example. The drain valve includes a twist-and-pull valve sleeve feature to manipulate the valve; however, the valve sleeve remains on the drain valve and therefore cannot be lost or misplaced. The valve sleeve further includes an easy grip for opening and closing the valve.
Claims19
A fluid drain valve comprising:
- a valve body defining a first threaded end, a second end, and a first passageway extending through the valve body from the first aid to the second end, to valve body farther defining a plurality of openings at the second end, wherein the valve body further includes at least one pin extending outward from the valve body,
- a first o-ring mounted on one side of the plurality of openings,
- a second o-ring mounted on the opposite side of the plurality of openings, and
- a valve sleeve mounted to the valve body and over the plurality of openings, the valve sleeve defining a second passageway and a sleeve opening, wherein the valve sleeve further includes at least one slot that mates with the at least one pin,
- whereby when the valve sleeve is manipulated, fluid may flow through the plurality of openings in the valve body and out the sleeve opening.

A fluid drain valve comprising:
- a valve body defining a first threaded end, a second end, and a first passageway extending through the valve body from the first end to the second end, the valve body further defining a plurality of openings at the second end forming by a plurality of support ribs,
- a first o-ring mounted on one side of the plurality of openings,
- a second o-ring mounted on the opposite side of the plurality of openings, and
- a valve sleeve mounted to the valve body and over the plurality of openings, the valve sleeve defining a second passageway and a sleeve opening, wherein the valve sleeve define an open valve position and a closed valve position, and wherein the second o-ring permits fluid to pass trough the sleeve opening when the valve sleeve is in the open valve position and prevents fluid from passing through the sleeve opening when the valve sleeve is in the closing valve position,
- whereby when the valve sleeve is manipulated, fluid may flow through the plurality of openings in the valve body and out the sleeve opening.

A fluid drain valve comprising:
- a valve body defining a cylindrical shaped body having a first threaded end, a conical shaped second end, and a first passageway extending through the valve body from the first end to the second end, the valve body further defining a plurality of openings at the second end, the valve body further including at least one pin extending outward from the valve body,
- an o-ring mounted at the second end of the valve body, and
- a valve sleeve mounted to the valve body and over the plurality of openings, the valve sleeve defining a second passageway and at least one arcuate shaped slot that mates with the at least one pin,
- whereby the valve sleeve defines an open valve position and a closed valve position, and wherein the o-ring permits fluid to pass though the second passageway when the valve sleeve is in the open valve position, and prevents fluid from passing though the second passageway when the valve sleeve is in the closed valve position.
