Abstract
A pressure-fed brush may be used for efficient painting. The elastomeric bladder member inside the brush member is provided with a plurality of slots which separate the pressure-fed V-slots into separate fingers, thereby allowing flexing over irregular surfaces. A flow control restrictor is also provided to allow the flow fed to the brush to be varied according to the nature and viscosity of the materials being used. By providing such a flow controller, the need to feather or otherwise modulate the valve at the brush is removed. The handle and valve assembly may be utilized with different size brush heads by provision of different intermediate members which retain varying size bladders for use with varying size brush members.
