Abstract
A cylinder apparatus includes a piston and a cylinder tube including a first end and a second end. The cylinder tube is formed to include a central bore extending from the first end to the second end for receiving the piston therein and a second bore extending from the first end to the second end spaced apart from the central bore. The cylinder apparatus also includes a first end cap coupled to the first end of the tube and a second end cap coupled to the second end of the tube. The second end cap is formed to include a first port in communication with the central bore of the tube and a second port in communication with the second bore. First end cap and second end cap have similar configurations and use substantially identical seals. Therefore, the semi-finished parts of the present invention have substantially identical configurations, regardless of the specific embodiment selected for a particular use. Ports and fittings can be selectively added either to the semi-finished first end cap or to the semi-finished second end cap to customize each finished cylinder for use in a particular environment.
