  • Apparatus to prevent side load in hydraulic override pumps
    Patent number: 11353012
    Abstract: An example apparatus to prevent side load in hydraulic override pumps includes a lever rotatably mounted to a support. The apparatus includes a pump cylinder rotatable about a first end of the pump cylinder. The apparatus also includes a pump rod operatively coupled to the lever to move within the pump cylinder based on rotation of the lever. The pump cylinder rotates when the pump rod moves within the pump cylinder.

  • Manual hydraulic override pumps for use with actuators
    Patent number: 11118612
    Abstract: Manual hydraulic override pumps for use with actuators are described herein. An example apparatus includes a manifold including a reservoir port to be fluidly coupled to a reservoir of fluid, a pump port to be fluidly coupled to a pump, a first actuator port to be fluidly coupled to a first chamber of an actuator, and a second actuator port to be fluidly coupled to a second chamber of the actuator. The example apparatus also includes a rotor disposed in a cavity formed in the manifold. The rotor is rotatable between a first actuating position in which the rotor fluidly couples the first actuator port and the pump port, and a second actuating position in which the rotor fluidly couples the second actuator port and the pump port.
