Abstract: An absolute valve position detector with self-powering capabilities is provided. An energy-harvesting position sensor is activated by the rotation of a pinion that rotates according to the opening and closing of the valve. The sensor outputs an electrical pulse that may be simultaneously used to provide power to the position detector and to indicate the rotation of the pinion and, therefore, the position of the valve. In a preferred example, the energy-harvesting sensor is activated by change in a magnetic field and the magnetic polarization of a Wiegand wire. In examples, the electrical pulse is induced in a coil wrapped around the Wiegand wire when a magnet disposed on the pinion is rotated.

Abstract: An actuator assembly includes a cylinder disposed in an actuator housing, the cylinder having a cylinder interior is in fluid communication with a source of pressurized fluid. A ram member has a piston head within the cylinder interior, and pressure on the piston head moves the ram member. An end of the ram member acts on a collar having a collar interior, and an end of a rod member is disposed within the collar interior. The rod member is displaceable relative to the collar such that the end of the rod member does not contact the collar. Accordingly, fluid in the cylinder interior acting on the ram member may expand due to thermal expansion without damaging a hard stop at an opposite end of the rod member and without losing system pressure by triggering a relief valve.

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.

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: 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: Se describe métodos y aparatos para cargar acumuladores. Un sistema dado como ejemplo para cargar un aparato acumulador incluye un piston dispuesto dentro de un alojamiento de manera de definir una primera cámara adyacente a un primer lado del piston y una segunda cámara adyacente a un segundo lado del piston. Una sonda de llenado, que tiene un cuerpo y un pasadizo entre un primer extremo de la sonda de llenado y un segundo extremo de la sonda de llenado, se acopla de manera removible al piston para acoplar, en una comunicacion fluídica, el pasadizo de la sonda de llenado a la segunda cámara del alojamiento, cuando el acumulador se halla en una condicion de carga. Hay una válvula acoplada en una comunicacion fluídica al piston, destinada a permitir el flujo del fluido hacia la segunda cámara del alojamiento por intermedio del piston, cuando la sonda de llenado está acoplada al piston.
