Filed:

Sep 15, 2022

Appl. No.:

17/945590

Inventors:

- Minneapolis MN, US
Bryan K. Colby - New Brighton MN, US

International Classification:

F04B 9/04
F04B 17/03
F04B 49/20
F04B 49/12

Abstract:

Non-limiting exemplary embodiments of a pumping system and methods for operating the pumping system in a region of high pressure or a region of high flow are disclosed. The pumping system includes a piston disposed within a piston cylinder, a drive shaft, an eccentric coupled to the drive shaft, a connecting arm having opposing first and second ends, and a controller for controlling the rotation of the drive shaft such that the piston oscillates within a region of high pressure or a region of high flow.

Abstract:

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.
