Nikhil M. Arya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11459987
    Abstract: A valve assembly for a pump includes an electrical actuator having a stator and an armature. The stator includes an annular outer stator portion and an annular inner stator portion, and an annular channel formed radially between the outer stator portion and the inner stator portion. A first radial channel extending through the annular outer stator portion between an outer surface of the outer stator portion and the annular channel, and at least one second opening in the annular outer stator portion results in magnetic symmetry of the stator. Upon activating the electrical actuator, the attraction of the armature towards the stator is uniform thus displacing fluid between the stator and armature in a uniform manner and to avoid high velocity, potentially damaging fluid flow.
    Type: Grant

  • Patent number: 10060421
    Abstract: A cryogenic fluid pump includes a plurality of pumping elements, each of the plurality of pumping elements having an actuator portion that is associated with and configured to selectively activate one end of a pushrod in response to a command by an electronic controller, an activation portion associated with an opposite end of the pushrod, and a pumping portion associated with the activation portion. For each of the plurality of pumping elements, the pumping portion is activated for pumping a fluid by the activation portion, which activation portion is activated by the actuator portion. The electronic controller is configured to selectively activate each of the plurality of pumping elements such that a flow of fluid from the cryogenic fluid pump results from continuous activations of the plurality of pumping elements at selected dwell times between activations of successive pumping elements.
