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.

Abstract: The position indicator is applicable to submerged valves forming part of hydraulic systems for the transfer of liquids or gas, based on that the corresponding signal which is obtained as a consequence of the state or position (open or closed) of the valve is transmitted by hydraulic pressure, from a long distance and transformed into an analog or digital signal which can be viewed on a display screen. 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).
