摘要： An assembly includes an inlet tube and an outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube. The solenoid assembly has a spring urging the plunger to the closed position. The assembly includes a first pressure sensor positioned to be compressed when the plunger is moved toward the open position. Pressure detected by the first pressure sensor indicates whether the plunger is at the open position. The assembly includes a second pressure sensor positioned to be compressed when the plunger is moved toward the closed position. Pressure detected by the second pressure sensor indicates whether the plunger is at the closed position.

摘要： An assembly includes an inlet tube and an outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube, the solenoid assembly having an induction coil surrounding the plunger. The assembly includes a Hall effect sensor that detects a magnetic field of the solenoid assembly. The assembly includes a computer in communication with the Hall effect sensor, the computer having a processor and memory that stores instructions executable by the processor to identify a resistance of the induction coil based on data from the Hall effect sensor, and to determine whether the plunger is at the closed position based on the identified resistance of the induction coil.
