6629825, Oct 7, 2003

Filed:

Nov 5, 2001

Appl. No.:

10/011470

Inventors:

Mark Stickland - Cornelius NC
Jason Hunt - Mooresville NC
Stephen Sharp - Cornelius NC

Assignee:

Ingersoll-Rand Company - Woodcliff Lake NJ

International Classification:

F04B 1700

US Classification:

417362, 417360, 41742315, 418DIG 1

Abstract:

An air compressor unit having an enclosure with a base. A motor is rigidly mounted to the base, and the motor drives both an airend and an impeller. The airend is pivotally mounted with respect to the base. The airend is directly connected to a horizontal separator tank, and the separator tank supports the airend. The airend and separator tank comprise a single integrated unit, and the separator tank is pivotally mounted to the base. The motor is a dual shafted motor having a drive side shaft and a non-drive shaft extending from opposite ends of the motor. A drive system is coupled to the drive side shaft and transfers power from the motor to the airend. The drive system is a belt and pulley system, and the airend is pivoted with respect to the motor to adjust belt tension. The impeller is coupled to the non-drive side shaft.

Appl. No.:

11/111269

Inventors:

Michael John Lucas - Mooresville NC, US
James David Gillon - Kannapolis NC, US
Jason William Hunt - Charlotte NC, US

Assignee:

Ingersoll-Rand Company - Montvale NJ

International Classification:

F01N 7/08

US Classification:

181249, 181212, 181229, 181230, 181247

Abstract:

A pulsation dampener for receiving a fluid medium containing pressure pulsations. The pulsation dampener can include a body having an inner surface, an inlet, and an outlet, and a fluid path defined at least partially by the inner surface of the body. The fluid path can include a first chamber in fluid communication with the inlet and having a first cross-sectional area, a second chamber positioned adjacent the first chamber and having a second cross-sectional area different from the first cross-sectional area, and a third chamber in fluid communication with the outlet and positioned adjacent the second chamber opposite the first chamber and having a third cross-sectional area different from the second cross-sectional area. The fluid path can be configured such that the second cross-sectional area is greater than the first cross-sectional area and the third cross-sectional area.

International Classification:

F01N 1/00

US Classification:

181249

Abstract:

A method of attenuating fluid dynamic pulsations that propagate through a flow of fluid at a convective velocity of the fluid, the pulsations having an organized vortical structure includes directing the flow to a pulsation dampener inlet having a first area and transitioning the organized vortical structure to a small-scale turbulent structure by squeezing the vorticies by passing the flow of fluid through a passage having a second area that is smaller than the first area, then rapidly expanding the flow of fluid by passing it into a chamber having a third area measured at an inlet of the chamber that is substantially larger than the second area. The method also includes discharging the flow of fluid from the chamber. The flow of fluid includes substantially attenuated fluid dynamic pulsations and acoustic pulsations that travel through the flow of fluid at the speed of sound.
