Your car has a cam-shaft that controls the positioning of the cylinder valves. It MAY contact the valves directly, but in most cars they are not close together. To transmit the action of the cams to the valves they might have used rocker arms and lengths of metal. Those lengths of metal are called lifters. An improved version uses a tube filled with oil and are called hydraulic lifters.
