  • Patent number: 11346167
    Abstract: Described herein is a system for relieving pressure in a drillstring on a drilling rig. The system includes a remote switch which moves from a closed-valve position to an open-valve position. The system also includes a valve actuator which moves from a first valve actuator position to a second valve actuator position when the remote switch moves from the closed-valve position to the open-valve position. The system further includes a valve to route a drilling fluid from the drillstring to a flowline via a bleed-off line when the valve moves from a closed position to an open position as the valve actuator moves from the first valve actuator position to the second valve actuator position.

  • Patent number: 9567953
    Abstract: A noise from a fuel pump module is reduced by housing a port injection (PI) fuel pump in a pump case of a fuel tank, in a structure in which the PI fuel pump is held with a bracket that is provided at a position between the PI fuel pump and a PI suction filter. The PI fuel pump and the bracket that engages with the pump case are interposed by an elastic member that abuts a base part of the bracket. In operation, when the PI fuel pump transmits its vibration to the pump case through the elastic member and the bracket, the elastic member dampens and reduces the vibration transmitted to the bracket, thereby reducing the noise by a reduction of transmitted vibration through the pump case to a subtank and the fuel tank.

The position of the valve (2) is set by the position of an actuator shaft (3′) to which are secured cams (11) so that the rotation of the shaft causes the cams (11) to act on hydraulic cartridges (12), thereby regulating the position of said cartridges, and as a consequence, regulating the pressure of a secondary hydraulic system to provide said pressure signal which can be converted to any type of reliable indication, corresponding to the real position of the valve (2).
