Abstract
Female quick couplings have a housing defining an axial bore therethrough that has a frustum-shaped bore portion that defines a restriction orifice, a first slot transverse to the axial bore, an a first shoulder between the first slot and the restriction orifice, and a locking member slidingly received in the first slot. The frustum-shaped bore can have an upstream conical frustum and a downstream conical frustum mated at their respective smaller diameter. The upstream conical frustum has a largest diameter that is larger than a largest diameter of the downstream conical frustum. Engine systems incorporating the female quick coupling and female quick coupling kits are also disclosed.
