It is proposed an assembly comprising a plastic container and a component attached to the container by means of an attachment system, the container having a circular attachment portion. The attachment system comprises: - a ring shaped member (1) comprising a top flange (11), a bottom flange (12) and a frustoconical side wall (13) connecting the top flange and the bottom flange, the bottom flange and a portion of the frustoconical side wall being embedded in the attachment portion, the ring shaped member further comprising peripheral tabs (14); - a plurality of engaging claw parts, each engaging claw part being configured to engage a peripheral tab and to press the component against the attachment portion.
摘要:
Method for spill-free refilling for a liquid solution selective catalytic reduction, SCR, an exhaust after-treatment technology for diesel engines. The method includes the steps of establishing a liquid-tight connection between a coupling part of a tank ( 37 ), and a coupling part of a dispensing nozzle of a gun ( 9 ) for spill-free refilling. A system for spill-free refilling of liquids and a gun for spill-free refilling of liquids, a connection for a vehicle tank, a method and a system for control and communication in a spill-free liquid re-filling system, a method and a system for media provision in a spill-free refilling system, a spill-free and liquid-tight refilling connection and computer programme products are disclosed.
摘要:
An isolation valve has a housing having a vent path and a sealing member that opens and closes the vent path. The sealing member is driven by a motor via a gear arrangement that links the sealing member with the motor. The motor drives the gear arrangement in a first direction to open the vent path and a second direction to close the vent path. During operation, a motor current rises when the sealing member reaches the first position and/or the second position. The controller detects the motor current rise and changes operation of the motor (e.g., stops the motor) in response.
摘要:
Ein Tankschutzanordnung zur Verhinderung von Falschbetankung eines Kraftfahrzeugs enthaltend eine an einer Zapfsäule (14) vorgesehene, säulenseitige RFID-Sicherungskomponente (16) mit einer kraftstoffabhängigen Codierung und einem RFID-Lesegerät und eine zum Kraftfahrzeug gehörige, fahrzeugseitigen RFID-Sicherungskomponente (20), die mit der säulenseitigen Sicherungskomponente (16) zusammenwirkt und mit einer Codierung für einen für das Fahrzeug zugelassenen Kraftstoff versehen ist, wobei die Sicherungskomponenten (16, 20) mittels drahtloser Datenübertragung kommunizieren, ist dadurch gekennzeichnet, dass das RFID-Lesegerät (16) induktiv aufladbar ist.
摘要:
A fuel transfer apparatus (10) for providing fuel to a vehicle engine from a plurality of fuel tanks. A transfer pump (22) is positioned intermediate a pair of fuel tanks (24, 26) and is operable to transfer fuel therebetween. Fuel is provided to the engine from a first one of the two fuel tanks. Excess fuel is returned to the first one of the two fuel tanks. When the level in the first fuel tank is less than the level in the second fuel tank by a predetermined amount, the transfer pump transfers an amount of fuel from the second fuel tank to the first fuel tank. Fuel level sensors (32) are utilized to monitor the level of fuel in the two fuel tanks and report to a microprocessor (40) which controls the transfer pump. The microprocessor utilised to control the transfer pump may be incorporated into the transfer pump, may be a stand alone microprocessor, or may comprise an existing vehicle circuit board such as, e.g., the electronic control module (ECM). A three-way valve (54) may be incorporated into the transfer pump so that the transfer pump can be additionally utilised to provide a priming feature for an engine driven fuel pump.
