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.

A vibration-limiting stabilizer system for an electrical valve actuator in a shutoff valve of a fluid supply system comprising:
- a stabilizer including a fitting having a tube section forming a fluid supply conduit and extending between a first mounting flange structured to couple with a valve housing of the shutoff valve and a second mounting flange;
- the stabilizer further including a strongarm attached to the fitting and including a first side wall connected to the first mounting flange, and a second side wall connected to the second mounting flange, and the first side wall and the second side wall extending outwardly from the first mounting flange and the second mounting flange, respectively, to a clamp mount;
- and
- the stabilizer further including a clamp positionable upon the clamp mount and including at least one clamping element structured for clamping a solenoid assembly of the electrical valve actuator to the strongarm.
A vibration-limiting stabilizer comprising:
- a fitting including a tube section forming a fluid supply conduit and having a first tube section end and a second tube section end, a first mounting flange extending peripherally around the fluid supply conduit and connected to the first tube section end, and a second mounting flange extending peripherally around the fluid supply conduit and connected to the second tube section end;
- and
- a strongarm attached to the fitting and including a clamp mount, a first side wall extending between the first tube section end and the clamp mount, a second side wall extending between the second tube section end and the clamp mount, and at least one stiffening wall extending between the first side wall and the second side wall.
A vibration-limiting stabilizer comprising:
- a one-piece casting including a fitting having a tube section forming a fluid supply conduit and extending between a first tube section end and a second tube section end;
- a first mounting flange connected to the first tube section end and extending peripherally around the fluid supply conduit;
- a second mounting flange connected to the second tube section end and extending peripherally around the fluid supply conduit;
- a strongarm attached to the fitting and including a clamp mount, a first side wall extending between the first mounting flange and the clamp mount, and a second side wall extending between the second mounting flange and the clamp mount and oriented diagonally relative to the first side wall.
