  • Patent number: 10859071
    Abstract: A rotary traveling valve for subterranean pumping system is disclosed herein. The traveling valve includes a rotary lock configured for back and forth rotary motion in response to up stroke and down stroke movements of a driver. The bottom face of the rotary lock rests against a seating face of a housing of the valve, and a fluid passage in the seating face is opened due to rotary motion of the rotary lock during a down stroke movement of the driver, and closed during an up stoke movement of the driver. The bottom face of the rotary lock is pressed against the sealing face by a back pressure spring to prevent excessive bottom pressure to cause pumping interruption due to gas and fluid blow-by through the valve. It also compensates for any wear that may take place on the two surfaces. In addition traveling valve incorporates bearing balls to minimize friction between moving parts such as driver and housing as well as between driver and rotary lock.

  • Patent number: 10852041
    Abstract: A two temperature electronic expansion valve control for variable speed compressors that utilizes a correlation between airflow percentage and heat exchanger pressure drop to control the operation of an expansion valve. An indoor airflow percentage request may be communicated from an outdoor controller to an air handler controller. Using a correlation between airflow percentage and pressure drop across the heat exchanger, the airflow percentage may be used in predicting an outlet pressure of refrigerant exhausted from the heat exchanger. The predicted pressure drop may be used in determining a saturated temperature for the exhausted refrigerant. The determined saturated temperature may be compared to a sensed temperature of the refrigerant at the outlet of the heat exchanger to determine a superheat value, which is compared to a reference superheat value in determining the degree to open or close the expansion valve.

  • Patent number: 9851725
    Abstract: A drive control device and method for an electric expansion valve is disclosed. In the disclosure, before applying a drive pulse signal corresponding to a rotary pulse number to a motor of the electronic expansion valve, a secondary positioning is performed on a relative position between stator magnetic field of the motor and rotor magnetic field of the motor by applying a holding current of a first duration time to the motor, applying an pulse signal of an additional pulse number to the motor, and applying a holding current of a second duration time to the motor, and a same secondary positioning operation is also performed on the motor after applying the drive pulse signal corresponding to the rotary pulse number to the motor of the electronic expansion valve, which ensures that the electronic expansion valve operates according to the drive pulse signal corresponding to the rotary pulse number.
