  • Three-way control valve
    Patent number: 10215304
    Abstract: A 3-way high-speed valve including a housing, first and second spools, and an actuator mechanism. The spools are slidably disposed in bores of the housing. The housing further defines an inlet, first and second intermediate ports, and first and second outlets. The inlet is fluidly open to the first bore. The intermediate ports each fluidly connect the first and second bores. The first and second outlets are fluidly open to the second bore. The actuator mechanism articulates the spool bodies to generate differing flow conditions of the valve, including a first flow condition in which the inlet is fluidly connected to the first outlet, and a second flow condition in which the inlet is fluidly connected to the second outlet.
