Abstract
A power tool may include a body arranged to support a rotatable work tool. The body may include a front handle and a rear handle. The front handle may be arranged between the rotatable work tool and the rear handle. The power tool may further include a liquid dispensing system for adding a controlled amount of liquid to the rotatable work tool. The liquid dispensing system may include a valve for adjusting a flow of liquid in the liquid dispensing system. The valve may include a control member arranged on a portion of the body separate from the front handle but adjacent to the front handle such that the control member is operable by a hand gripping the front handle.
Claims17
A power tool comprising a body arranged to support a rotatable work tool rotatable about an axis of rotation, the body comprising a front handle and a rear handle, the power tool comprising a liquid dispensing system for adding a controlled amount of liquid to the rotatable work tool, the liquid dispensing system comprising a valve for adjusting a flow of liquid in the liquid dispensing system, wherein the valve is configured to be controlled by a control member arranged on a portion of the body at which at least part of a conduit transporting the liquid to the rotatable work tool is embedded in the body and separate from the front handle, but adjacent to the front handle such that the control member is operable by a hand gripping the front handle,
- wherein the power tool is an electrically powered tool comprising a battery compartment arranged between the front handle and the rear handle, wherein the valve and the control member are arranged between the battery compartment and the front handle,
- wherein the axis of rotation is contained in a plane disposed parallel to a baseline of the power tool, and
- wherein the valve and the control member are disposed immediately proximate to one another on a same side of the plane as a majority of the front handle in a wedge-shaped volume between the front handle and the battery compartment.
A method for controlling an amount of liquid added to a rotatable work tool during operation of a power tool, the power tool comprising a body arranged to support the rotatable work tool rotatable about an axis of rotation, the body comprising a front handle and a rear handle, wherein the front handle is arranged between the rotatable work tool and the rear handle, the method comprising;
- arranging the power tool to comprise a liquid dispensing system for adding a controlled amount of liquid to the rotatable work tool, the liquid dispensing system comprising a valve for adjusting a flow of liquid in the liquid dispensing system, wherein the valve comprises a control member arranged on a portion of the body at which at least part of a conduit transporting the liquid to the rotatable work tool is embedded in the body and separate from the front handle, but adjacent to the front handle, and
- controlling the amount of liquid by operating the control member with a hand which is simultaneously gripping the front handle,
- wherein the power tool is an electrically powered tool comprising a battery compartment arranged between the front handle and the rear handle, wherein the valve and the control member are arranged between the battery compartment and the front handle,
- wherein the axis of rotation is contained in a plane disposed parallel to a baseline of the power tool, and
- wherein the valve and the control member are disposed immediately proximate to one another on a same side of the plane as a majority of the front handle in a wedge-shaped volume between the front handle and the battery compartment.
A power tool comprising a body arranged to support a rotatable work tool, the body comprising a front handle and a rear handle, the power tool comprising a liquid dispensing system for adding a controlled amount of liquid to the rotatable work tool, the liquid dispensing system comprising a valve for adjusting a flow of liquid in the liquid dispensing system, wherein the valve is configured to be controlled by a control member arranged on a portion of the body at which at least part of a conduit transporting the liquid to the rotatable work tool is embedded in the body and separate from the front handle, but adjacent to the front handle such that the control member is operable by a hand gripping the front handle,
- wherein the power tool is an electrically powered tool comprising a battery compartment arranged between the front handle and the rear handle, wherein the valve and the control member are arranged between the battery compartment and the front handle,
- wherein the battery compartment is arranged inclined at an angle with respect to a baseline of the power tool, thereby defining a wedge-shaped volume between the front handle and the battery compartment, and
- wherein the valve and the control member are disposed immediately proximate to one another in the wedge-shaped volume and on a same side of a plane of the power tool wherein a majority of the front handle is located.
