ABSTRACT:
A novel self-metering and dispensing device for fluids obtained from a pressurized fluid supply is provided. Tubing and valving means permit the introduction of fluid into and discharge from a closed cylindrical reservoir. The reservoir contains a slideably disposed piston coacting with a coil compression spring, piston travel determining the amount of fluid in the reservoir. Once the determined amount of fluid is introduced into the reservoir, the fluid is discharged by the force of the coil compression spring acting upon the piston.
