Patent attributes
A pressure regulating device for a liquid includes a main hollow body having an inlet end and an outlet end for the liquid, which are connected via a longitudinal passage, a tubular valve member, which is slidingly accommodated in the passage and has a regulating end upstream from the flow of the liquid, a seat placed inside the passage, upstream from the valve member, and having a transverse surface formed in the passage to interact with the regulating end of the valve member and define therewith a part having an adjustable width for the liquid. The seat is eccentrically supported in the passage and is formed of one piece with the main body, and is supported proximate to the inlet end for the liquid by a pair of longitudinal support wings substantially parallel to the flow direction.
