Abstract
A hand-held trigger operated spray gun for dispersing high pressure liquids. The spray gun includes a control valve assembly which has a first annular coil spring for maintaining a valve seat in position and a second annular coil spring for biasing a valve ball into closing engagement with the valve seat. The valve ball is sized such that the valve seat retaining spring retains it in centered relation to the ball biasing spring even when subjected to high liquid pressure fluctuations. The spray gun further has an improved sealing and trigger lock features.
