ABSTRACT:
A flush device comprising an inlet and an outlet chamber separated by a wall also includes two apertures in the wall. One of the apertures has a small diameter, the other having a large diameter. A serpentine-shaped capillary tube is formed along the wall surface in the inlet chamber and coaxial with the axis of the larger diameter aperture. The exit end of the tube is connected to the smaller diameter aperture for providing a controlled fluid path from the inlet to the outlet chamber. A plunger is positioned coaxially with the axis of the larger diameter aperture and is biased to normally close the larger diameter aperture. The plunger also is operative to open the larger diameter aperture for forming a large diameter path for fluids for a flush operation.
