Abstract
A reversing mechanism for a pneumatically or hydraulically powered tool having a rotor adapted to selectively rotate in either one of first and second rotational directions. The reversing mechanism allows a user to actuate a button that rotates a valve to direct air flow through the tool. By pressing the button, the button will move a base laterally, and in doing so, rotates the valve. Rotating the valve distributes fluid to cause the rotor to rotate in a selected rotational direction.
Claims31
A tool having opposing first and second sides and powered by a fluid including a motor having a rotor that rotates in either of first and second rotational directions, the tool comprising:
- first and second buttons respectively disposed on the first and second sides;
- a base disposed between and operatively coupled to the first and second buttons;
- a valve having a valve axis and that is adapted to selectively direct the fluid to cause the rotor to rotate in either one of the first and second rotational directions;
- and
- a link arm rotatably coupled to the base and slidably and rotatably coupled to the valve,
- wherein linear movement of the base causes the link arm to rotate the valve about the valve axis.
A reversing mechanism for a tool powered by a fluid and having a rotor operable to drive an output lug in either one of first and second rotational directions, the mechanism comprising:
- a base coupled to first and second buttons;
- a valve having a valve axis and adapted to selectively direct the fluid to cause the rotor to drive the output lug in either one of the first and second rotational directions;
- and
- a link arm rotatably coupled to the base and slidably and rotatably coupled to the valve,
- wherein movement of the base causes the link arm to rotate the valve about the valve axis.
A valve rotatable about a valve axis to selectively direct fluid to cause a rotor of a tool to drive an output lug of the tool in either one of first and second rotational directions, the valve comprising:
- a valve inlet;
- a valve outlet;
- a projection adapted to abut a housing of the tool;
- a channel disposed between the projection and the valve outlet and adapted to direct fluid away from a valve to housing rotary connection;
- and
- a slot adapted to be slidably and rotatably coupled to a link arm, wherein the link arm is adapted to cause rotational movement of the valve about the valve axis in response to linear movement
- of first and second buttons of a reversing mechanism, the first and second buttons respectively disposed on first and second sides of the tool.
