Connection arrangement and method for assembling the same

A method for assembling a connection arrangement for mechanically and fluidly connecting a fuel filter to a fluid meter in a fuel dispenser comprising a first part, a second part and a filter holding part along a common centre axis, wherein:

• said first part comprises:
• an outlet for fluid communication with an inlet of said fluid meter,
• a first connection interface for mechanical connection to said fluid meter,
• an inlet for fluid communication with the filter holding part, and
• a second connection interface for mechanical connection to said second part;
• said second part comprises:
• a third connection interface for mechanical connection to said second connection interface, and
• a fourth connection interface for mechanical connection to said filter holding part;
• said filter holding part comprises:
• an outlet for fluid connection to said inlet of said first part, and
• a fifth connection interface for mechanical connection to said fourth connection interface;
• said method comprising the steps of
• connecting the third connection interface of the second part to the second connection interface of the first part,
• connecting the filter holding part to a fuel supply pipe,
• connecting the fifth connection interface of said filter holding part to the fourth connection interface of the second part by advancing the filter holding part into an opening formed through a sidewall of the second part in a direction toward the centre axis, establishing an unlocked state of said connection arrangement, in which said filter holding part is rotatable around said centre axis, and
• adjusting the second part so as to press the filter holding part against the first part, thereby establishing a locked state in which projections extending from the filter holding part are seated in recesses formed in the first part so as to prevent rotation of the filtering holding part around said centre axis.

A connection arrangement for mechanically and fluidly connecting a fuel filter to a fluid meter in a fuel dispenser, the connection arrangement comprising:

• a first part;
• a second part;
• and
• a filter holding part, all of the first, second, and filter holding parts being connected along a common centre axis;
• wherein:
• said first part comprises:
• an outlet for fluid communication with an inlet of said fluid meter,
• a first connection interface for mechanical connection to said fluid meter,
• an inlet for fluid communication with the filter holding part, and
• a second connection interface for mechanical connection to said second part;
• said second part comprises:
• a third connection interface for mechanical connection to said second connection interface, and
• a fourth connection interface for mechanical connection to said filter holding part;
• said filter holding parts comprises:
• an outlet for fluid connection to said inlet of said first part, and
• a fifth connection interface for mechanical connection to said fourth connection interface;
• the second part is adjustable to move said connection arrangement between an unlocked state, in which said filter holding part is rotatable around said centre axis, and a locked state, in which the filter holding part is pressed directly against the first part and the filter holding part is prevented from rotating around said centre axis and has a sealed fluid connection to the first part;
• the second part has an opening formed through a sidewall thereof, the filter holding part being configured to be advanced into the opening in a direction toward the centre axis so as to mechanically connect the fifth connection interface to the fourth connection interface;
• the first part has recesses formed therein;
• the filter holding part has projections extending therefrom;
• and
• in the locked state, the projections are seated in the recesses, thereby preventing rotation of the filter holding part from rotating around said centre axis.
