  • Patent number: 10894262
    Abstract: An electrostatic sprayer system for dispensing and dispersing a liquid containing a spray compound includes a spray cloud dispersal feature that reduces the time that a residual spray cloud containing droplets including the spray compound remains suspended after spraying. A method of dispersing the residual spray cloud is implemented by a control system that causes a flow control system to deliver a non-active gas or liquid in conjunction with stopping delivery of the liquid containing the spray agent and charged with the same polarity, so that a charged cloud of the non-active gas or liquid, which may be air, displaces the suspended active fluid particles. The non-active gas or liquid may be dispensed for a predetermined time interval as determined by the control system, or the operator may control the time interval during which that the non-active fluid is dispensed.

  • Patent number: 10870135
    Abstract: A pressure washer includes a pump for pressurizing a primary fluid flow, the pump including a pump inlet for receiving fluid from a common fluid source and a pump outlet for supplying a pressurized primary fluid and a jet pump including a primary fluid inlet fluidly coupled to the pump outlet, a secondary fluid inlet configured to receive fluid from the common fluid source, and a fluid outlet. In a high pressure operating mode, all of the pressurized primary fluid flows through the jet pump and exits through the fluid outlet of the jet pump. In a high flow operating mode, all the pressurized primary fluid flows through the jet pump and entrains a secondary fluid supplied through the secondary fluid inlet from the common fluid source so that the secondary fluid also flows through the jet pump, resulting in a combined fluid flow of the primary fluid and the secondary fluid that exits through the fluid outlet of the jet pump.
