  • Fluid supply system having shutoff valve with stabilized electrical valve actuator
    Patent number: 11566592
    Abstract: A fluid supply system for a machine such as an internal combustion engine includes a shutoff valve having an electrical actuator that includes a solenoid subassembly, and a stabilizer for the electrical valve actuator. The stabilizer includes a fitting structured to couple the shutoff valve to adjacent hardware in the fluid supply system, and a strongarm extending between the fitting and the solenoid assembly and clamped to the solenoid subassembly. A vibration-damping reinforced grommet may be clamped between the solenoid subassembly and the clamp.
    Type: Grant
    Filed: May 13, 2021
    Date of Patent: January 31, 2023
    Assignee: Caterpillar Inc.
