  • Patent number: 4645178
    Abstract: Multiple drive paths are provided between the valve plunger and force motor of a direct drive valve and force motor assembly whereby should one of the drive paths fail, the force motor can still be used to drive the valve plunger through another drive path. One of the drive paths consists of a drive shaft having one end drivingly connected to an eccentric on the motor output shaft and the other end connected to the end of the valve plunger remote from the motor output shaft. The drive shaft is desirably provided with an enlarged head portion having a flat annular surface on the axial inner end thereof in close proximity to a corresponding flat end face on the end of the valve plunger closest to the motor output shaft, whereby should the valve plunger break, the drive shaft will hold the valve plunger together and allow for degraded valve performance.
