Abstract
The invention relates to a water gun, in particular to a toy water gun comprising a supply line, which is adapted to supply a pressurized liquid from a source, a nozzle arrangement for ejecting the liquid to the environment as well as a valve for controlling a flow of the liquid in a direction from the supply line to the nozzle arrangement. The water gun additionally includes a flow-smoothing device, with the valve arranged behind the flow-smoothing device with respect to the flow direction.
Claims16
A water gun comprising:
- a pressurized liquid source,
- a supply line,
- a valve,
- a nozzle arrangement,
- wherein:
- the supply line fluidly connects the pressurized liquid source with the valve,
- the nozzle arrangement is configured to eject liquid from the pressurized liquid source to an environment,
- the valve is positioned in between the supply line and the nozzle arrangement and is configured to control a flow of the liquid from the pressurized liquid source in a flow direction from the supply line to the nozzle arrangement,
- the valve includes a valve seat and a movably-supported valve body, the valve body having a first position, in which the valve body attaches to the valve seat in a sealing manner,
- an electromechanical actuator coupled with the valve body and configured to displace the valve body substantially parallel to the flow direction into a second position,
- a handle portion configured to grip the water gun,
- a nozzle portion disposed to face away from the handle portion and including the nozzle arrangement, and
- a pump device that includes
- (a) a pump inlet in fluid communication with a liquid inlet of the water gun and
- (b) a pump outlet in fluid communication with the pressurized liquid source, wherein the liquid inlet is arranged in the nozzle portion or adjacent to the nozzle portion.
