Abstract
A drain tool assembly adapted to couple to a housing without causing fluid to flow from the housing until moved to a draining position. The drain tool assembly avoids fluid spillage by sealing a body to the housing and then engaging a plunger of the housing by moving and locking a sleeve to initiate a flow of fluid from the housing.
Claims13
A drain tool assembly for draining fluid contained in a housing that includes a plunger, the drain tool assembly comprising:
- an adapter including first and second adapter ends, a threaded portion disposed proximate the first adapter end and adapted to be threadably coupled to the housing, and a circumferential rim disposed between the threaded portion and the second adapter end, wherein the circumferential rim has a substantially circular cross-section and includes a slot extending from the second adapter end to the threaded portion;
- an inner body disposed in and extending through the adapter and adapted to allow the fluid to flow from the housing through the drain tool assembly, the inner body including first and second inner body ends, wherein the first inner body end forms an outwardly extending flange, and wherein the inner body includes a groove adapted to receive a coupling mechanism;
- and
- an outer body coupled in an axial direction to the inner body via the coupling mechanism and adapted to slidably engage with the slot to be selectively disposed in one of either a non-draining position, wherein the fluid in the housing does not flow through the drain tool assembly, and a draining position, wherein the inner and outer bodies are axially moved relative to the adapter and the fluid in the housing flows through the drain tool assembly,
- wherein when the inner and outer bodies are disposed in the draining position, the outer body is not slidably engaged with the slot to allow the outer body to rotate relative to the adapter, and the circumferential rim is adapted to retain the outer body in the draining position when the outer body is not engaged with the slot and is rotated relative to the adapter.

A drain tool assembly for draining oil contained in an oil filter canister housing that includes a spring-loaded plunger and a female threaded fitting, the drain tool assembly comprising:
- an adapter including first and second adapter ends, a threaded portion disposed proximate the first adapter end and adapted to threadably couple to the fitting, and a circumferential rim disposed between the threaded portion and the second adapter end, wherein the circumferential rim has a substantially circular cross-section and includes a slot extending from the second adapter end to the threaded portion;
- an inner body disposed in and extending through the adapter and adapted to allow the oil to flow from the housing through the drain tool assembly, the inner body including a groove adapted to receive a snap-ring;
- and
- an outer body coupled in an axial direction to the inner body via the snap-ring and adapted to slidably engage with the slot to be selectively disposed in one of either a non-draining position, wherein the oil in the housing does not flow through the drain tool assembly, and a draining position, wherein the inner and outer bodies are axially moved relative to the adapter and the oil in the housing flows through the drain tool assembly, wherein when the inner and outer bodies are disposed in the draining position, the outer body is not slidably engaged with the slot to allow the outer body to rotate relative to the adapter, and the circumferential rim is adapted to retain the outer body in the draining position when the outer body is not engaged with the slot.

A drain tool assembly for draining fluid contained in a housing that includes a plunger, the drain tool assembly comprising:
- an adapter including first and second ends, a threaded portion disposed proximate the first end and adapted to be threadably coupled to the housing, and a circumferential rim disposed between the threaded portion and the second end, wherein the circumferential rim has a substantially circular cross-section and includes a slot extending from the second end to the threaded portion;
- an inner body disposed in and extending through the adapter and adapted to allow the fluid to flow from the housing through the drain tool assembly;
- and
- an outer body coupled in an axial direction to the inner body and including a protrusion adapted to slidably engage with the slot, wherein the protrusion is adapted to slide relative to the slot to move the outer and inner bodies between non-draining and draining positions, wherein the fluid in the housing does not flow through the drain tool assembly when the inner and outer bodies are disposed in the non-draining position, and the fluid in the housing flows through the drain tool assembly when the inner and outer bodies are disposed in the draining position, and
- wherein when the inner and outer bodies are disposed in the draining position, the protrusion is not slidably engaged with the slot to allow the outer body to rotate relative to the adapter, and the circumferential rim is adapted to retain the outer body in the draining position when the protrusion is not engaged with the slot.
