Abstract: A housing for a fuel dispensing unit comprises a top part, a bottom part and at least one column extending between the bottom part and the top part. Said bottom part comprises a light emitting device arranged to emit light, and said top part comprises a light directing device for directing the emitted light towards the bottom part.

Abstract: A fluid pump for a fuel dispensing unit comprises a pump housing with a first chamber and a second chamber, each chamber having a fluid inlet valve and a fluid outlet valve, respectively. The chambers are separated by a movable piston arranged to repeatedly decrease and increase the volumes of the chambers. The piston comprises a magnetic device, and electromagnetic control means are configured to move the piston by altering a magnetic field, for repeatedly decreasing and increasing the volume of the chambers.

Abstract: A system including a pulse-generating device can comprise of at least one analog sensor and at least one unit for signal-processing is arranged to detect the analog signal and to generate signal changes having a higher frequency. When generating signal changes in connection with the determination of the amount of fuel dispensed from a fuel pump unit and a frequency generator for generating a periodic analog signal having a frequency is generated, which corresponds to a fuel volume flow in the pump unit. The amplitude of the analog signal is detected and then signal changes having a higher frequency are emitted, which is dependent on and higher than the frequency.

Abstract: In a method for dispensing liquid fuel at a filling station, which comprises at least two delivery nozzles which each via a fuel line with associated metering means are in fluid communication with a fuel container, the fuel is made, when a large flow of fuel from a selected delivery nozzle is required to flow from the fuel container to the selected delivery nozzle via at least two fuel lines with associated metering means.

Abstract: A fuel pump unit (1) for dispensing fuel comprises a fuel container (2), a fuel conduit (4) connected to the fuel container (2), and a metering means (11) which is arranged in the conduit (4) to measure a flow of fuel therethrough. The metering means (11) comprises a first metering unit (14) to measure the flow of fuel within a first flow range, and a second metering unit (12) to measure the flow of fuel within a second flow range. The first flow range comprises larger flows of fluid than the second flow range.

Abstract: A device on a conduit end for joining the conduit (1) to a coupling (4) or some other receiver of the end of the conduit, which is made of aluminum or an aluminum alloy. Two external annular beads (2, 2′) are pressed out from the conduit wall on the conduit end and accommodate between themselves an O-ring (3). In an arrangement for joining, the receiver (4) has a conical inlet and means, which together with the rear annular bead (2) form engaging means for a tightening means.

Abstract: An apparatus for volume determination in a pump unit for fluid, such as fuel, in which a first and a second metering means are provided which are juxtaposed. The metering means each comprise a metering casing having a shaft assembly, which is adapted to be rotated when fluid flows through the metering casing. Each metering means further comprises a pulse generating means, which has a frequency generator and a pulse generator and which is adapted to convert the rotation of the shaft assembly into pulses. The frequency generator is connected to the shaft assembly for rotation therewith, mounted in the respective metering casings. The two pulse generators are adapted to sense, in a contactless manner, rotation of the respective frequency generators and to emit pulses in relation thereto. The two pulse generators are arranged in a separate pulse generator module and are encompassed in a pulse generator casing, which is detachably connected to the metering casing.
