Abstract
A shaft seal assembly (55) for use in a rotary fluid pressure device. The device includes a housing (51) and a rotary shaft (31). The shaft seal assembly (55) includes an elastomeric sealing element (65), an inner support member (67) and an outer support member (69). The sealing element (65) includes a cushion portion (81) disposed radially between the inner and outer support members to cushion radial movement of the inner support member when the shaft moves radially. The sealing element (65) includes a sealing lip (71) defining a pivot point (83) and the inner support member extends rearwardly of the pivot point (83), whereby radial movement of the inner support member results in corresponding radial movement of the sealing lip (71), reducing the loading on the lip.
