Abstract: The present invention provides housing member for a rotary fluid powered actuator including a cylindrical housing member having an opening in at least one end, a head member received on each open end of the housing where each head has a central aperture in generally aligned relation with the longitudinal axis of the housing, a shaft member to extend through the central aperture for rotation therein and journal means to journal the shaft in the housing adjacent each end thereof and a vane member to extend outwardly from the shaft member for rotation therewith in response to fluid pressure in the housing where the housing member includes at least one stator member, integral therewith extending radially inwardly from the sidewall of the housing and adapted to receive a seal member to provide a seal between the termination of the stator and the shaft and members extending along a portion of the length of the housing to define bolt passages, and bolt members to be received in the bolt passage where the bolt member

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.
