<p>The piston-cylinder assembly has a piston (14) carrying a seal (32) to contact the cylinder (12). The latter also has a seal (20) to contact the piston. The seal on the piston projects radially outwardly of the piston and that on the cylinder projects radially inwardly of the latter. On increase of pressure from the fluid source, the seals on the piston and cylinder are radially deformed toward the inner surface of the cylinder and the outer surface of the piston respectively to increase sealing contact. The seals on the cylinder and piston are respectively formed integrally with them.</p> |
