Abstract: A water ejecting gun simultaneously produces two kinds of ejecting flows, a straight flow and a spray flow. The gun disposes a rotating or spiral fan element in a water passage for producing the spray flow. The straight flow acts as a carrier for the spray flow. A mechanism for producing the spray and straight flows includes an inner sleeve, an outer sleeve rotatably and axially movable on the inner sleeve, a nozzle element disposed in the inner sleeve which defines a main flow passage and a sub-flow passage and a frusto-conical core element engaging the upstream end of the nozzle element to form a variable gap therebetween. When the gap is open, water flows to the main flow passage. When the gap is closed, a smaller water flow to the main flow passage occurs through radial and axial passages in the core element. The straight and spray water flows exit the gun simultaneously through an ejecting opening.

Abstract: This invention relates to a pressing device for a hose coupler in which the end of the hose is interposed between the inner and outer pipes of the hose coupler, and in which said external pipe is compressed by uniformly pressing gainst its outer periphery upper and lower dies and a pair of side dies so that the hose end can be secured between the internal and external pipes of the hose coupler.
