    Abstract: A variable performance valve for use in a fuel nozzle is presented. The valve includes a spring, an inner spool having a port, an outer sleeve, and an orifice, which in a fuel nozzle application may be a calibration orifice. In a low flow condition, the inlet to downstream pressure is the spring force divided by the area on which the pressure acts. At low flow the orifice does not cause any appreciable pressure drop. As the flow increases, a pressure drop develops across the orifice. Since the pressure drop across the valve cannot be greater than the spring force divided by valve area, the valve is forced to open to compensate. As flow is increased, the valve will stroke completely open and the pressure drop at the port becomes negligible and the pressure drop across the orifice is nearly 100% of the pressure drop across the valve.

    Abstract: This invention relates to a flow rate control valve device for controlling and supplying a pressure oil flow rate from a pressure oil supply source to a pressure chamber of an actuator such as a hydraulic cylinder of a working machine of construction equipment. The flow rate control valve device includes a main spool (13) inserted slidably into a valve hole bored in a valve main body (10) so as to connect or cut off a main port (11) for controlling a flow rate, which communicates with the pressure chamber of the actuator, with or from a drain port (12) communicating with a tank (25), and equipped with a plurality of notch grooves (23) formed on the peripheral surface of a large diameter portion (14) at one of its ends in an axial direction and a seat (17) formed on one end side; a spring (18) interposed between the deep end surface of the valve hole and one end surface of the main spool and biasing the seat of the main spool to make pressure contact with a seat (19) formed on the valve main body; and a device (20) for pushing the main spool from its other end surface side against the resilient force of the spring in such a manner as to allow the main port to communicate with the drain port through the notch grooves. In this manner, the sliding motion of the main spool (13) can be controlled accurately and finely with high response and high precision flow rate control can be carried out.

    Abstract: An example valve includes: (i) a valve body defining a longitudinal cavity, where the valve body includes a supply inlet and an operating outlet; (ii) a cage disposed in the longitudinal cavity, where the cage includes (a) a first opening fluidly coupled to the supply outlet, and (b) a second opening fluidly coupled to the operating outlet; and (iii) a spool mounted within the cage and configured to move axially therein. When the valve is actuated, the spool moves within the cage to form a gap, thereby allowing pressurized fluid to flow from the supply inlet through the first opening, the gap, and the second opening to the operating outlet. A flow area defined around an exterior peripheral surface of the spool changes upstream from the gap at a first rate, and changes downstream from the gap at a second rate that is different from the first rate.
