ABSTRACT:
A metering valve device being particularly adapted for the precision control of metering minute quantities of fluids and the like from a high pressure environment to a low pressure environment, even to a vacuum. The metering valve device having a cylindrical core and an inlet and an outlet. The inlet is connected to a radially disposed duct that extends to and forms an opening on the surface of the core, while the outlet is connected to a V-shaped slot positioned on the surface of the core in space relation to the opening. A sleeve that is slidably mounted on the core has a portion that forms a leakproof chamber between the core and the sleeve at the position of the opening and a seal-tight engagement of the core at the position of the V-shaped slot. Upon sliding the sleeve so as to permit a desired part of the V-shaped slot to be brought within the confines of the chamber, a controlled volume of high pressure fluid may be dispensed through the device. The sleeve and core are provided with correlated micrometer-type vernier scale and markings whereby the volume flow that is desired may be readily attained.
