Abstract: A pump includes a coaxially integrated pump relief valve element (50) of high density polymer material that seats against a hard metallic sleeve (32). The sleeve (32) is pressed into a first counterbore (22) around the relief flow channel (20) with an interference fit. That axial end of the sleeve bearing the valve seat face projects, for a substantial proportion of the sleeve length, beyond the first counterbore shoulder into a second, larger diameter counterbore space (28) to provide an annular space (30) around the outside diameter surface of the sleeve to free the seat face end of the sleeve from direct structural restraint.
