Embodiment Construction

[0045] The following detailed description is merely exemplary in nature and is not intended to limit the invention or limit the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description.

[0046] like figure 1 and 2 As shown in , some embodiments may include an automotive system 100 including an internal combustion engine (ICE) 110 having an engine block 120 defining at least one cylinder 125 having Piston 140 is coupled to rotate crankshaft 145 . Cylinder head 130 cooperates with piston 140 to define combustion chamber 150 . A fuel and air mixture (not shown) is disposed in combustion chamber 150 and is ignited, generating thermally expanding exhaust gases that cause piston 140 to reciprocate. Fuel is provided through at least one fuel injector 160 and air is provided through at least one intake port 210 . Fuel is provided to fuel injecto...

Abstract

A quick fit connector is disclosed for the return line of fuel injectors in an internal combustion engine. The connector includes a T- or L-shaped connector body having at least one connection branch insertable in a fuel return port of a fuel injector, a lower plate, an upper plate and a spring clip. The upper plate is slidingly mounted on the spring clip and the connector body and is movable between an unlocked position, in which the spring clip is in unloaded condition and free from any engagement with the fuel injector, and a locked position in which the spring clip is in loaded condition and engages the fuel injector and the lower plate.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to UK Patent Application No. 1514389.4, filed 13 August 2015, the entirety of which is incorporated herein by reference. [0003] FIELD OF THE INVENTION The present invention relates to connectors for low pressure hydraulic circuits and, in particular, the present invention relates to quick fit connectors for connecting injector return ports to fuel return lines. Background technique [0004] Internal combustion engines are provided with injectors, such as electrically actuated solenoid injectors, which, thanks to their combined electrical and hydraulic actuation, ensure a large number of pulses at high fuel pressures. This type of injector is basically made of a high-pressure hydraulic valve and a low-pressure electric actuation valve, which is used to change the hydraulic state of the high-pressure hydraulic valve. Accordingly, such injectors require a low pressure circuit to discharge...
