Claims
- 1. A brake actuator, comprising:a housing defining an enclosed chamber therein having an opening through an end wall of said housing; a reciprocal pushrod supported for reciprocal motion in said housing chamber having an end portion extending through said opening in said end wall of said housing; a pair of mounting bolts affixed to said end wall of said housing on opposed sides of said opening; and said end wall of said housing having a recessed offset portion surrounding said mounting bolts and a projecting relatively thin generally flat contact surface generally circumscribing said recessed offset portion.
- 2. The brake actuator defined in claim 1, wherein said recessed offset portion is generally diamond-shaped including end portions surrounding said mounting bolts and a midportion surrounding said opening through said end wall of said housing.
- 3. The brake actuator defined in claim 2, wherein said contact surface has a constant width surrounding said diamond-shaped recessed offset portion on opposed sides.
- 4. The brake actuator defined in claim 3, wherein the remainder of said end wall on opposed sides of said contact surface is recessed from said contact surface such that said contact surface is limited to said relatively thin contact surface.
- 5. A brake actuator, comprising:a housing defining an enclosed chamber therein having an end wall including a central opening therethrough; a reciprocal pushrod supported for reciprocal motion in said housing having an end portion extending through said opening in said end wail of said housing; a pair of mounting bolts affixed to said generally flat end wall of said housing on opposed sides of said opening; and said end wall of said housing having a generally diamond-shaped recessed offset portion, said recessed offset portion including end portions surrounding said bolts and a midportion surrounding &aid opening and a flat projecting contact surface on opposed sides of said offset recess portion generally circumscribing said offset recessed portion.
- 6. The brake actuator defined in claim 5, wherein said projecting contact surface comprises relatively thin sharply rounded bands on opposed sides of said recessed offset portion.
- 7. The brake actuator defined in claim 6, wherein said end wall of said housing is generally circular and the remainder of said end wall on opposed sides of said contact surface is recessed from said generally flat contact surface.
