Pump comprising an axially acting spring gasket

A pump for applying fluid to an assembly, the pump comprising:

• a pump housing including
• a circumferential wall surrounding a delivery chamber of the pump;
• an end-facing wall having an outer end-facing surface facing axially positioned away from the delivery chamber;
• an inlet for receiving fluid into the delivery chamber;
• an outlet for the fluid which emerges from the outer end-facing surface via the delivery chamber;
• a delivery member which rotates within the delivery chamber, the delivery member delivering fluid within the delivery chamber from a low-pressure side of the pump which contains the inlet to another portion of the delivery chamber located on a high-pressure side of the pump which contains the outlet;
• and
• an axial gasket being a spring gasket, the spring gasket fully encircles the outlet over 360° when viewed in an axial view of the pump in order to separate the outlet from the low-pressure side of the pump, wherein the spring gasket is annularly self-contained within the pump and is one of a disc spring or a hollow-profile spring or a V-profile spring or a bellows spring, and during operation of the pump the spring gasket performs
• (i) a function of sealing the outlet of the pump housing from the low-pressure side of the pump, and
• (ii) a function of a pressing device to keep the circumferential wall of the pump housing engaged to the end-facing wall of the pump housing in a fluid-tight axial pressure contact so that the spring gasket alone performs the function of sealing the outlet of the pump housing from the low-pressure side of the pump.
