<p>A method of making a seal between a piston (14) and a cylinder bore (8) involves matching the external profile of a piston ring (10a) to the profile of the cylinder wall. The piston ring (10a) is fixed to the piston (14) to prevent rotation of the ring (10a), and the piston (14) is located within the cylinder bore (8) so that the complementary surfaces of the piston ring (10a) and the cylinder bore (8) are mated.</p> |
