Patent number: 7581302Abstract: A magnetic gap in a solenoid core is formed by a non-magnetic brazing material bonded into a groove encircling the core in the region of the magnetic gap. A bore through a single piece core and valve cartridge is dimensioned to intersect the brazing material and remove magnetic material bridging the gap without severing the core into separate pieces. This allows the solenoid core and the valve cartridge to be machined in a single piece with a uniform diameter bore receiving a single piece solenoid plunger and valve spool. This ensures accurate concentricity of the plunger and spool within the bore, which improves magnetic performance while reducing manufacturing costs.Type: GrantFiled: January 13, 2005Date of Patent: September 1, 2009Assignee: G. W. Lisk Company, Inc.Inventor: Jeffery A. Tyler

Publication number: 20050005919Abstract: A servomechanism for a valve controlling engine intake flow via a cooler and a bypass uses a proportional solenoid operating a hydraulic valve to power a hydraulic actuator setting the position of the control valve. An engine sensor and electric controller provide input to the proportional solenoid, and feedback from the position of the control valve is applied to the hydraulic valve by a cam and spring applying a force in opposition to the proportional solenoid.Type: ApplicationFiled: July 8, 2003Publication date: January 13, 2005Inventor: Jeffery Tyler

Patent number: 5318354Abstract: An electrically actuated valve for regulating a working pressure of a closed volume load includes an inlet valve (24) for controlling fluid flow between a supply port (16) and a working port (18) and an outlet valve (26) for controlling fluid flow between the working port (18) and an exhaust port (20). A solenoid actuator (70) applies an adjustable force to a movable valve element (44) for closing the outlet valve (26) and opening the inlet valve (24). The adjustable force is opposed by a reactionary force that is generated by the working pressure. The movable element (44) includes opposing areas exposed to the working pressure for scaling the reactionary force to the working pressure.Type: GrantFiled: October 16, 1992Date of Patent: June 7, 1994Assignee: C. W. Lisk Company, Inc.Inventor: Jeffery A. Tyler

Patent number: 5234265Abstract: A brake valve for an automatic brake system includes an actuator responsive to feedback pressure from a brake for regulating pressure in the brake proportional to an electrical signal applied to the actuator. The actuator exerts a force that is opposed by feedback pressure acting against a predetermined area of the actuator. Valves operated by the actuator provide for alternately communicating a supply of pressurized air to the brake cylinders or discharging air pressure from the cylinders. A low-flow vent valve provides for discharging small quantities of air from my valve. However, a pilot operated high-flow dump valve supersedes the low-flow vent valve for discharging larger quantities of air and permits my valve to be controlled by smaller actuating forces.Type: GrantFiled: February 18, 1992Date of Patent: August 10, 1993Assignee: G. W. Lisk Company, Inc.Inventor: Jeffery A. Tyler
