  • Publication number: 20180304292
    Abstract: 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.

  • Publication number: 20180298885
    Abstract: 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.
