Publication number: 20170333927Abstract: First and second fluid components are individually pumped to a device from first and second pumps. A first volumetric flow rate of the first fluid component discharged from the first fluid component is measured. A second volumetric flow rate of the second fluid component discharged from the second pump is measured. Operation of at least one of the first and second pumps is controlled based on the measured first volumetric flow rate and the measured second volumetric flow rate to produce a target ratio of the first fluid component and the second fluid component at the device.Type: ApplicationFiled: May 11, 2017Publication date: November 23, 2017Inventors: Daniel P.

Patent number: 9027849Abstract: In an electric airless sprayer (16), as the motor (14) temperature approaches allowable limits, several performance cutbacks can be used to prevent overheating. The preferred method is to gradually reduce the controlled pressure. If the temperature continues to rise, the control (20) switches to on/off or deadband control. If the temperature continues to rise in spite of these measures, the control (20) shuts the unit down.Type: GrantFiled: December 29, 2004Date of Patent: May 12, 2015Assignee: Graco Minnesota Inc.Inventors: Robert J. Lind, Robert G. Gilbert

Publication number: 20140263451Abstract: A pumping system comprises a pump, first and second channels, a valve, and an actuator. The pump pumps fluid according to a pumping cycle. The first channel has a first fluid flow orifice with a first diameter, while the second channel has a second fluid flow orifice with a second diameter greater than the first diameter. The valve is configured to direct fluid from the pump to the first channel in a first state, and to the second channel in a second state. The actuator is configured to switch the valve into the first state during a high pressure period of the pumping cycle, and into the second state during a low pressure period of the pumping cycle.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: GRACO MINNESOTA INC.Inventors: Daniel P.
