Embodiment Construction

[0016] While the invention may take embodiments in many different forms, preferred embodiments of the invention are shown in the drawings and will be described in detail herein, it being understood that this disclosure is to be considered as an introduction to the principles of the invention examples, and are not intended to limit the broad aspects of the invention to the illustrated embodiments. As used herein, the term "present invention" is not intended to limit the scope of the claimed invention, but is a term used to discuss exemplary embodiments of the invention for descriptive purposes only.

[0017] The present invention broadly relates to a flow guide placed in the pressurized region of the cylinder chamber of a motor (also called kidney ports due to their shape). The inducer acts as a barrier between the main inlet to the motor and the inlet to the cylinder chamber and directs air or fluid to the vane lifter port of the motor before it flows to the inlet to the cylin...

Abstract

The present invention relates broadly to a flow diverter disposed in a plenum area of a motor cylinder chamber (also referred to as kidney ports). The flow diverter acts as a barrier between a main inlet to the motor and an inlet to the cylinder chamber, and directs air or fluid to vane lifter ports of the motor before the air or fluid flows to the inlet to the cylinder chamber. In addition, the flow diverter can serve to regulate air or fluid flowing into the cylinder chamber to control power of the tool. The flow diverter allows for numerous options of where the main inlet to the motor can be positioned and provides a means of regulating the air or fluid flowing into the cylinder chamber.

Description

technical field [0001] The present invention relates to a mechanism for directing the flow of air or fluid in a pneumatic tool. Background technique [0002] Many tools are powered by pneumatic air or hydraulic fluid. For example, an impact wrench applies torque to a workpiece to loosen or tighten it. In conventional tools, the air inlet of the motor is located adjacent to the vane lifter port of the motor. This positioning of the air inlet requires air to flow into the vanes lifter port of the motor and behind the vanes to deploy the vanes before a large amount of air enters the cylinder chamber of the motor. However, the location of the air inlet near the blade lifter port limits the type of motor that can be used with the air tool. Contents of the invention [0003] The present invention broadly relates to a flow guide placed in the pressurized region of the cylinder chamber of a motor (also called kidney ports due to their shape). The inducer acts as a barrier betw...
