ABSTRACT:
The invention is an automatic flow control valve. The rolling cluster of a olamite is biased by the constant force due to the vertical component of gravity on the mass of the rolling cluster. The band of the rolling cluster progressively covers or exposes a porous passage which is integral with one of the rolling planes of the rollamite. Fluid flows through the porous passage and past the rollamite band.
The rolamite valve of this invention may be selectively modified to become, alternately, a remotely operated fluidic control valve, an automatic self-regulating volumetric flow control valve, an automatic self-regulating flow control valve for maintaining a constant output pressure, a vapor trap valve, and an automatic self-regulating flow control valve for maintaining a constant input pressure.
