Patent number: 11896992Abstract: A mix chamber for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mix chamber includes a chamber body extending between a first end and a second end and including flat lateral sides. A ramp feature is disposed proximate the first end and is configured to contact and push first and second side seals, respectively, away from a body axis as the mix chamber shifts in a first direction through a cartridge bore to increase a gap between the first side seal and the second side seal such that the first side seal engages the first flat lateral side and the second side seal engages the second flat lateral side.Type: GrantFiled: August 12, 2022Date of Patent: February 13, 2024Assignee: Graco Minnesota Inc.Inventors: Daniel P. Ross, Joseph E. Tix, Samuel R. Stewart, Mark T. Weinberger, Christopher J. Pellin, Jeffrey N. Velgersdyk, Jack A. Bosak, Jacob R. Whiteoak

Patent number: 9849475Abstract: A mobile spray dispenser comprises a fluid circulation system and a heating unit. The fluid circulation system has a motorized pump capable of circulating fluid from a fluid reservoir in a high-pressure spray mode and a low-pressure recirculation mode, and of providing the fluid to a sprayer. The motorized pump draws lower power in the low-pressure recirculation mode than in the high-pressure spray mode. The heating unit is disposed within the fluid circulation system to heat the fluid to a target temperature, and comprises a primary heater and a boost heater. The primary heater is configured to be active during both the high-pressure spray mode and the low-pressure recirculation mode. The boost heater is in fluid series with the primary heater, and is configured to be active only during the low-pressure recirculation mode.Type: GrantFiled: December 16, 2013Date of Patent: December 26, 2017Assignee: Graco Minnesota Inc.Inventors: Christopher J. Pellin, Jeffrey N. Velgersdyk, Joshua D. Roden, Bryan K. Colby
