Flow restrictor apparatus utilizes a pair of relatively movable disks. One disk includes an output bore communicating with a groove cut into one face of the disk. The groove is generally circular in configuration. The other disk includes an input bore which communicates with the groove in the opposite disk when the two disks are assembled together. Varying the location of the input bore relative to the groove varies the flow of fluid through the apparatus. A pair of O-rings seal the groove and the two disk elements. A second embodiment utilizes a metering disk disposed between two fixed disks. The fixed disks include aligned bores for input and output, and the metering disk includes aligned grooves on the surfaces which face the fixed disks and a bore through the metering disk joining the aligned grooves.
