Abstract:
A brake actuator comprises a piston working in a cylinder with a seal carried by the piston for engagement with the outermost wall of the cylinder and a seal housed in the innermost wall of the cylinder for engagement with the piston. Each seal is of triangular outline and is received in a seal-receiving groove which has first and second relatively inclined end walls with which faces on the seal are in full facial engagement, and a sealing region for engagement with the wall of the cylinder or the piston is defined by and between the third remaining face and the adjacent face of the seal. A space is provided between the second end wall and the third face to accommodate any deformation of the material of the seal which is otherwise confined between the piston and the cylinder.
