Patent number: 11873807Abstract: A pressure washer may include a pump configured to receive a relatively low pressure fluid inlet and provide a relatively high pressure fluid outlet. The pressure washer may also include an engine coupled with the pump for driving the pump. An electric starter may be engageable with the engine for starting the engine. A flow sensor may be configured to provide a control signal in response to detecting fluid flow through the pump. The pressure washer may also include a controller configured to actuate the electric starter in response to the control signal when the engine is not operating.Type: GrantFiled: July 26, 2017Date of Patent: January 16, 2024Assignee: FNA GROUP, INC.Inventors: Gus Alexander, Paulo Rogerio Funk Kolicheski, Michael C Hansen, Javier Penuelaz

Patent number: 11446693Abstract: A pressure washer gun is provided including a safety locking feature that may inhibit unintentional actuation. In an embodiment, the pressure washer gun may include a body portion, and a hand grip portion extending from the body portion. A trigger may be disposed adjacent to the hand grip portion and coupled with a flow control valve for controlling the flow of high pressure fluid through the pressure washer gun. A safety lock may be pivotally coupled with the hand grip portion for movement between a locked position inhibiting movement of the trigger to open the flow control valve, and an unlocked position allowing movement of the trigger to open the flow control valve, the safety lock being biased toward the locked position.Type: GrantFiled: April 25, 2018Date of Patent: September 20, 2022Assignee: FNA GROUP, INC.Inventors: Gus Alexander, Paulo Rogerio Funk Kolicheski, Richard J. Gilpatrick

Patent number: 11187214Abstract: In an embodiment, a pump includes a pump housing formed as a singular body. The pump housing may include a mounting feature adjacent a first end of the pump housing. The mounting feature may be configured for mounting the pump relative to a prime mover. A drive system cavity may be formed in the first end of the pump housing, and sized to receive at least a portion of an axial drive system. A pump cylinder may extend inwardly into the pump housing from the drive system cavity. A piston guide plate may be configured to be affixed within the drive system cavity. The piston guide plate includes a piston guide associated with the pump cylinder. The piston guide may be configured to at least partially receive a pump piston therethrough for facilitating alignment and axial movement of a pump piston within the pump cylinder.Type: GrantFiled: April 17, 2018Date of Patent: November 30, 2021Assignee: FNA Group, Inc.Inventors: Richard J. Gilpatrick, Gus Alexander, Paulo Rogerio Funk Kolicheski

Patent number: 10502197Abstract: In an embodiment, a variable flow pump may include a swashplate rotatably driven by a driveshaft. The swashplate may be movable between a first and second tilt angle relative to the driveshaft. A piston pump may be reciprocatingly driven by the swashplate based upon, at least in part, the tilt angle of the swashplate. An actuator piston may be moveable between a first and second position based upon, at least in part, a downstream backpressure of a fluid pumped by the piston pump. An actuator assembly may be moveable between a first and second position based upon, at least in part, the position of the actuator piston. The actuator assembly may include a swashplate driver configured urge the swashplate between the first and second tilt angles, and a biasing driver configured to apply a force urging the swashplate into contact with the swashplate driver.Type: GrantFiled: December 22, 2017Date of Patent: December 10, 2019Assignee: FNA Group, Inc.Inventors: Gus Alexander, Paulo Rogerio Funk Kolicheski

Patent number: 9682387Abstract: In an embodiment, a rotating nozzle including a generally cylindrical interior having an inlet at a circumferential wall adjacent a first end of the body portion and a generally axial exit adjacent a second end of the body portion. A nozzle portion is at least partially received within, and rotatable relative to, the cylindrical interior. The nozzle portion includes an at least partially conical shape, having a relatively smaller cross section adjacent the first end of the body portion. The nozzle portion defines a generally longitudinal flow passage having an inlet opening extending between an exterior of the nozzle portion and the flow passage adjacent the first end of the body portion and a generally axially oriented exit adjacent the second end of the body portion. The rotating nozzle further includes end cap disposed at least partially enclosing the cylindrical interior adjacent the first end of the body portion.Type: GrantFiled: November 17, 2015Date of Patent: June 20, 2017Assignee: FNA IP Holdings, Inc.Inventors: Gus Alexander, Paulo Rogerio Funk Kolicheski
