Abstract
Female quick couplings are disclosed that have a housing defining an axial bore having a first shoulder and a first slot transverse to the axial bore, a removable insert defining a restriction orifice seated against the first shoulder within the axial bore, and a locking member slidingly received in the first receptacle. The removable insert defines a restriction orifice having an upstream conical frustum and a downstream conical frustum mated at their respective smaller diameter. The upstream conical frustum has a largest diameter substantially similar to an internal diameter of the first sealing member and the downstream conical frustum has a largest diameter substantially similar to an internal diameter of the axial bore extending downstream of the first shoulder. The largest dimeter of the upstream conical frustum is larger than the largest diameter of the downstream conical frustum. Engine systems incorporating the female quick coupling are also disclosed.
