Patent number: 8739832Abstract: A valve arrangement includes an inlet conduit defining an inlet passage adapted for communication with a supply of pressurized motive fluid, a first planar surface spaced radially from the inlet conduit, first and second supply passages communicating through the first planar surface, and a rotary valve. The rotary valve includes a second planar surface abutting against the first planar surface and a valve passage communicating through the second planar surface. The rotary valve is rotatable to place the inlet passage in communication with a selected one of the first and second supply passages through the valve passage, and is adapted to conduct the pressurized motive fluid from the inlet passage to the selected one of the first and second supply passages.Type: GrantFiled: February 24, 2012Date of Patent: June 3, 2014Assignee: Ingersoll-Rand CompanyInventors: Randi J. Young, Nathanael S. Murphy

Patent number: 8011444Abstract: A locking assembly for the spindle of a tool includes a locking member, a biasing member interconnected with the locking member, and a collar surrounding a portion of the spindle. The spindle includes a spindle slot that receives the locking member to lock the spindle with respect to the tool housing. The collar may be rotated into an unlocked position in which the biasing member holds the locking member out of engagement with the spindle slot. The collar may also be rotated into a locked position in which a cam surface in the collar acts on the biasing member to apply a biasing force on the locking member toward engagement with the spindle slot. The biasing member may deflect to accommodate rotation of the collar into the locked position with the spindle slot not aligned with the locking member.Type: GrantFiled: April 3, 2009Date of Patent: September 6, 2011Assignee: Ingersoll Rand CompanyInventors: Douglas E. Pyles, Randi J. Young

Patent number: 7886840Abstract: A motor arrangement for a pneumatic tool includes a motor cylinder defining a motor chamber, an inlet passage adapted to receive a flow of motive fluid, forward and reverse passages communicating with the motor chamber, a throttle port, and at least one exhaust port. A motor rotor rotates in a forward direction in response to motive fluid flowing into the motor chamber from the forward passage and in a reverse direction in response to motive fluid flowing into the motor chamber from the reverse passage. A valve actuates to selectively place one of the forward and reverse passages in communication with the inlet passage for the provision of motive fluid from the inlet passage to the selected one of the forward and reverse passages. A throttle mechanism including a throttle actuator extends through the throttle port and is actuable to control the flow of motive fluid through the inlet passage.Type: GrantFiled: May 5, 2008Date of Patent: February 15, 2011Assignee: Ingersoll-Rand CompanyInventors: Randi J. Young, Nathanael S. Murphy
