Patent number: 11141742Abstract: A low flow compact spray head design for cleaning applications, especially for camera lens wash includes a miniature spray nozzle head which is about 5 mm in diameter or less for a single direction spray nozzle and about 8 mm in diameter of less for a nozzle with multiple sprays. The washer fluid is fed from the bottom of nozzle along a flow axis and is separated into two flows via two power nozzles or inlets which turn the flows 90° to become opposing jets impinging upon each other inside an interaction region. Uniform stream lines are generated by the two direct facing jets and converge at the nozzle throat to become a uniform spray fan, which is on a plane perpendicular to the axis of cylindrical nozzle head. This fluidic circuit design enables a miniature size low flowrate nozzle to operate well consistently with low flow rate (e.g.Type: GrantFiled: January 23, 2019Date of Patent: October 12, 2021Assignee: DLHBOWLES, INC.Inventor: Chunling Zhao

Patent number: 11117146Abstract: A spray system for an agricultural machine is configured to include a valving arrangement and multiple liquid product lines coupled to spray nozzle assemblies such that the valving arrangement can connect the product lines to the spray nozzle assemblies in different ways to achieve different modes of operation. Such modes can include providing agricultural liquid product flow through the spray nozzle assemblies at differing rates and/or flushing the product through the spray nozzle assemblies in differing directions. This can be achieved by controlling the valving arrangement to selectively connect any of the lines to pump for supplying product, to tank for returning product, or to block the lines to inhibit the flow of product. In one aspect, the product multiple lines can be of different sizes to enable more modes of operation, such as greater or lesser flow rates while spraying.Type: GrantFiled: March 20, 2019Date of Patent: September 14, 2021Assignee: CNH Industrial America LLCInventors: Roy A.
