Patent ID: 7481338

Claim:
A texturing system for applying a hardenable acoustic texture material to a surface comprising: a container assembly defining a container chamber; acoustic texture material arranged within the container chamber; propellant material arranged within the container chamber to pressurize the acoustic texture material; a housing supported within the container chamber, where the housing defines a housing chamber defining a housing inlet, where the housing inlet is configured such that the pressurized acoustic texture material is arranged within the housing chamber; a valve stem defining an inlet opening and an outlet opening, where the valve stem is supported for movement from a first valve stem position, through an intermediate valve stem position, and into a second valve stem position; a seal member that supports the valve stem relative to the container assembly; and a metering member supported relative to the valve stem within the housing chamber for movement between a first metering member position relative to the valve stem and a second metering member position relative to the valve stem; wherein when the valve stem is in the first valve stem position, the metering member engages the seal member to prevent fluid flow out of the container chamber by covering the inlet opening of the valve stem; when the valve stem is in the intermediate valve stem position and the metering member is in the first metering member position, pressurized texture material within the housing chamber flows into the inlet opening of the valve stem; and when the valve stem is in the second valve stem position and the metering member is in the second metering member position, the metering member engages the valve stem to prevent fluid flow out of the container chamber by covering the inlet opening of the valve stem.
