A self-cleaning orifice includes a housing having a bore defined therein. The bore includes a first diameter inlet portion and a second diameter outlet portion, with a seating surface defined between the inlet and outlet portions. A movable body having a seating surface with a groove defined thereon is disposed within the outlet portion of the bore. The body is movable relative to the housing to a first position in which the seating surface of the body is seated against the seating surface of the housing and provides a restricted flow between the inlet portion and the outlet portion of the bore The body is also movable relative to the housing to a second position in which the seating surface of the body is spaced apart from the seating surface of the housing creating an unrestricted fluid flow path between the inlet portion and the outlet portion of the bore.
