Latest Patents

Among his notable inventions is the **Warm-up Valve in a Variable Displacement System**. This innovative valve operates within a load-responsive hydraulic system, effectively connecting the pump discharge pressure with the pump compensator. It smartly bypasses a portion of the pump's capacity to the reservoir until the proper temperature is reached. At this point, a thermostatically controlled solenoid automatically closes the warm-up valve, allowing the pump to revert to a low-pressure standby mode.

Another significant contribution is the **Electro-Hydraulic Proportional Control Servo Valve**, which comprises a conventional control valve powered hydraulically by a double-acting cylinder. Controlled electrically through a double-acting solenoid paired with a variable D.C. supply, this valve showcases an advanced mechanism wherein the solenoid transmits varying forces to a four-way pilot valve. This pilot in turn regulates the positioning of the double-acting cylinder, featuring a neutral balance among the control valve spool and pilot spool through differing spring rates. This design allows for fine control, where even slight movements by the solenoid core can result in proportionally larger movements of the main control valve spool.
