Abstract
A regulating valve having anti-seize characteristics provides a linear drive system intermediate a drive shaft connected to a motor and a lifter connected to the regulator spring. The linear drive system translates the rotational motion of the drive shaft into preferably, linear only motion of the lifter, thereby preventing binding internal to the valve.
Claims14
A regulating valve comprising:
- a drive motor coupled to a drive screw;
- a linear drive system operably coupled to the drive screw;
- a lifter operably coupled to the linear drive system;
- a regulator spring applying a first force against the lifter in a first direction and against a regulator in a second direction, the first direction being opposite to the second direction;
- and
- a drive screw stop located opposite a portion of the lifter from the regulator spring, whereby the linear drive system translates rotational motion of the drive screw to linear motion in the first and second direction without rotation.

The regulating valve of 2 wherein the drive screw rotates the gear and the worm is restrained to linear motion.
A regulating valve comprising:
- a drive motor coupled to a drive screw;
- a linear drive system operably coupled to the drive screw;
- a guide;
- a lifter operably coupled to the linear drive system;
- a regulator spring applying a first force against the lifter in a first direction and against a regulator in a second direction, the first direction being opposite to the second direction;
- and
- a drive screw stop located opposite a portion of the lifter from the regulator spring;
- whereby the linear drive system translates rotational motion of the drive screw to linear motion in the first and second direction and the guide assists in limiting rotation of the lifter.

A regulating valve comprising:
- a drive motor coupled to a drive screw;
- a linear drive system operably coupled to the drive screw;
- a lifter operably coupled to the linear drive system;
- a regulator spring applying a first force against the lifter in a first direction and against a regulator in a second direction, the first direction being opposite to the second direction;
- and
- a drive screw stop located opposite a portion of the lifter from the regulator spring;
- whereby the linear drive system translates rotational motion of the drive screw to linear motion in the first and second direction of the lifter while preventing rotation being imparted by the drive screw to the lifter.
