Abstract
A connector, for example as shown in FIG. 1, for use in supplying fuel to a fuel injector comprises a tubular member arranged to be received, in use, within an opening provided in an engine cylinder head, the tubular member being shaped, at a first end thereof, for cooperation with part of the fuel injector, a second end of the tubular member being shaped for cooperation with an inlet adapter member. The inlet adaptor member is secured, in use, within the opening, the inlet adapter member and the tubular member defining a flow passage whereby fuel can be supplied, under pressure, to the fuel injector.
Claims17
A connector for use in supplying fuel to a fuel injector, said connector comprising a tubular member to be received, in use, within an opening provided in an engine cylinder head, said tubular member having first and second ends, said first end being shaped for cooperation with part of said fuel injector and said second end being shaped for cooperation with an inner end of an inlet adapter member which is secured, in use, within said cylinder head opening;
- said connector further comprising a flexible sleeve member having first and second ends, said first end of said sleeve member receiving a part of said second end of said tubular member and said second end of said sleeve member receiving a part of said inner end of said inlet adapter member;
- said inlet adapter member and said tubular member defining a flow passage whereby fuel can be supplied, under pressure, to said fuel injector.
A connector for use in supplying fuel to a fuel injector, said connector comprising a tubular member to be received, in use, within an opening provided in an engine cylinder head, said tubular member having a first end shaped for cooperation with part of said fuel injector, a second end shaped for cooperation with an inner end of an inlet adapter member which is secured, in use, within said cylinder head opening, and an outwardly extending part arranged to cooperate with said cylinder head so as to restrict angular movement between said tubular member and said cylinder head;
- said connector further comprising a seal arrangement whereby said connector is sealed to said cylinder head, said cylinder head opening and said tubular member defining a flow path whereby fuel at relatively low pressure can be returned from said fuel injector to a low pressure reservoir for fuel;
- said inlet adapter member and said tubular member defining a flow passage whereby fuel can be supplied, under pressure, to said fuel injector.
