Abstract A seal arrangement for use in a rotary actuator having a housing and an end wall where a shaft extends through an aperture in the end wall and and carries a vane, a stator assembly is provided and directly inwardly from the housing having an end edge in adjacent relation with the end wall and a longitudinal edge adjacent the shaft. A groove is provided extending longitudinally along the end edge and the longitudinal edge and is adapted to receive a generally rectangular stator seal member so the stator seal member end edge abuts the end wall to provide a fluid seal therebetween and where an annular groove is provided around the shaft receiving aperture and is adapted to receive a generally circular ring seal. The generally circular "O" ring seal includes a tab member having a thickness less than the thickness of the "O" ring member and the tab extends radially outwardly from the "O" ring member parallel to the groove of the end edge to engage the stator seal member.
A seal arrangement for use in a rotary actuator having a housing and an end wall where a shaft extends through an aperture in the end wall, the shaft carries a vane located in the housing and, a stator assembly is provided and directed inwardly from the housing having an end edge in adjacent relation with the end wall and a longitudinal edge adjacent the shaft; groove means are provided extending longitudinally along the end of the end edge and along the longitudinal edge and adapted to receive a generally channel shaped stator seal member where the stator seal member in the area of the end edge abuts the end wall to provide a fluid seal therebetween and where an annular groove is provided in the end wall around the shaft receiving aperture and adapted to recieve a generally circular ring seal, and where ring seal includes a radially outwardly extending tab member having a thickness less than the thickness of the ring member and extends parallel to the groove of the end edge to engage the stator seal member.
