Combination spray gun and pressure regulator.

摘要

An apparatus to regulate the pressure of liquid supplied to devices for the spray coating of articles for particular use in electrostatically paint spraying systems comprises a plurality of regulator valves (32) each having an inlet (74) in communication with a source (30) of pressurized liquid, an outlet (77) connected to a spray coating device, a valve member (48, 65) positioned therebetween, and a by-pass passage (35) connected to the inlet (74), the passages (35) of the regulator valves (32) being connected in series with each other so that liquid is supplied from the source (30) to each inlet (74) with the mimimum drop of pressure across any valve.
