  • Proportional hydraulic two-stage valve
    Patent number: 11473693
    Abstract: A valve includes a solenoid with a chamber housing a pin that actuates when the solenoid is energized. The valve also includes a spool housed within a sleeve. The sleeve includes a supply section with a supply port in communication with a supply source and a tank section with a tank port in communication with a reservoir. The spool includes a body including a first passage receiving fluid from the supply source when an opening for the first passage aligns with the supply port. When the solenoid is energized and the opening for the first passage aligns with the supply port, fluid from the supply source (i) applies a force to the spool body in a direction of actuation by the pin and (ii) flows to a second passage within the valve.
