Patent number: 11904194Abstract: A nozzle assembly includes a nozzle body, a first flow straightener coupled to the nozzle body, and a second flow straightener coupled to the nozzle body. The nozzle body defines an inlet, an outlet, and a nozzle body passage extending between the inlet and the outlet. The first flow straightener extends at least partially across the nozzle body passage and defines a first passage and a second passage each fluidly coupling the inlet and the outlet. The second flow straightener extends at least partially across the nozzle body passage and defines a third passage and a fourth passage each fluidly coupling the inlet and the outlet.Type: GrantFiled: March 15, 2021Date of Patent: February 20, 2024Assignee: Oshkosh CorporationInventors: Anthony J. Wroblewski, Brian D. Piller

Patent number: 10946226Abstract: A nozzle assembly includes a nozzle body and a flow straightener. The nozzle body defines an inlet configured to be fluidly coupled to fluid source, an outlet, and a nozzle body passage extending between the inlet and the outlet. The flow straightener is coupled to the nozzle body and extends at least partially across the nozzle body passage. The flow straightener defines a primary passage and a secondary passage extending through the flow straightener to fluidly couple the inlet and the outlet of the nozzle body. The primary passage defines a primary passage outlet having a cross-sectional area, and the secondary passage defines a secondary passage outlet having a cross-sectional area that is less than the cross-sectional area of the at least one primary passage. At least one of the primary passage outlet and the secondary passage outlet has a circular cross-section.Type: GrantFiled: January 7, 2019Date of Patent: March 16, 2021Assignee: Oshkosh CorporationInventors: Anthony J. Wroblewski, Brian D. Piller

Patent number: 8801393Abstract: A vehicle includes an engine and a liquid pump configured to pump liquid from a liquid intake system to an outlet. The vehicle further includes a pressure control system operably coupled to the engine via a communication connection, the pressure control system receiving a first signal from the engine representing engine speed. The pressure control system is configured to cause the liquid pump to change pumping pressure without changing the engine speed, and wherein the pressure control system is configured to cause the liquid pump to change pumping pressure without changing the engine speed when the pressure control system makes a determination relating to the engine speed.Type: GrantFiled: October 12, 2007Date of Patent: August 12, 2014Assignee: Pierce Manufacturing Inc.Inventors: Ryan W. Crabtree, David J Fieber, Brian D Piller, Chad M. Trinkner

Patent number: 6725940Abstract: A system for supplying a pre-determined ratio of liquid foam concentrate and water to a mixing device immediately upstream from a fire fighting nozzle. The system is electronically balanced by measuring pressure from a plurality of pressure signal sensors and transmitting said pressure signals to a controller unit. A foam additive pump is powered by a fixed displacement piston motor which in turn is electronically modulated independently of the level of operation of the water pump by a control system that is responsive both to the water pressure developed by the water pump and to the foam liquid concentrate pressure developed by the additive pump.Type: GrantFiled: May 10, 2000Date of Patent: April 27, 2004Assignee: Pierce Manufacturing Inc.Inventors: Andrew P. Klein, Thomas A. High, Kenneth A. Bolen, Jr., Brian D. Piller, Clarence A. Grady

Publication number: 20040020664Abstract: A system and method of maintaining a desired additive to water ration in a fire-fighting system including a water flow sensor configured to measure the water flow rate, a water pump, a hydraulic pump, a linear hydraulic cylinder driven by the hydraulic pump, an additive pump mechanically coupled to the linear hydraulic cylinder; and a pump displacement sensor configured to sense the position of the additive pump, the pump displacement sensor being in communication with the water flow sensor to maintain a pre-determined ratio of additive to water.Type: ApplicationFiled: August 2, 2002Publication date: February 5, 2004Applicant: Pierce Manufacturing Inc.Inventors: Robert P. Juidici, Clarence A. Grady, Andrew P. Klein, Brian D. Piller, Michael R. Moore
