Abstract: Methods and apparatus to charge accumulators are described An example system to charge an accumulator apparatus (100) includes a piston (104) disposed within a housing (102) to define a first chamber adjacent a first side (106) of the piston and a second chamber adjacent a second side (108) of the piston. A fill probe (202) having a body and a passageway between a first end (306) of the fill probe and a second end (308) of the fill probe removably couples to the piston to fluidly couple to the passageway of the fill probe to the second chamber of the housing when the accumulator is in a charging condition. A valve (142) is fluidly coupled to the piston to enable fluid flow to the second chamber of the housing via the piston (104) when the fill probe is coupled to the piston (104).

Abstract: Apparatus that prevent side load in hydraulic override pumps are disclosed herein. An example apparatus includes a lever rotatably mounted to a support, a pump cylinder rotatable about a first end of the pump cylinder, and a pump rod operatively coupled to the lever to move within the pump cylinder based on rotation of the lever, wherein the pump cylinder rotates when the pump rod moves within the pump cylinder.

Abstract: Universal control circuitry for an electro-hydraulic valve actuator system includes logic gate circuitry to control one or more of a closing solenoid valve, an opening solenoid valve, an emergency shutdown solenoid valve, and a hydraulic fluid pump motor to route hydraulic fluid through a hydraulic circuit to actuate a valve via a hydraulic actuator according to received commands. The universal control circuitry is configured to control operation for multiple different configurations of a hydraulic valve actuator system including double-acting configurations, single-acting spring-to-open configurations, and single-acting spring-to-close configurations, each with or without an emergency shutdown arrangement (which may be configured to trip based on an external shutdown input alone or in combination with a local system power failure), a hydraulic accumulator, and maintained or momentary input commands.

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.

Abstract: An example rotary actuator includes a cam that is to be coupled to a valve. The cam is rotatable about an axis. The example rotary actuator also includes a linear actuator having a stem movable along a path offset from and perpendicular to the axis and a chain having a first end and a second end opposite the first end. The first end of the chain is coupled to the stem and the second end of the chain coupled to the cam. The chain is disposed around at least a portion of an outer edge of the cam, and movement of the stem along the path rotates the cam about the axis.
