    摘要: An improved sealing arrangement 40 is provided for a replaceable cylinder liner 10. The sealing arrangement 40 includes a seal 26 in the form of a band that is positioned in an annular groove 28 under a flange seat 20 of the cylinder liner 10. The annular groove 28 includes a first and a second undercut 30,34 that provides a relief area for the seal 26 to deflect into lessening the opportunity of damage to the seal 26. The first and second undercuts 30,34 also relieve stress in the axial direction improving the fatigue life of the cylinder liner10.

    摘要: A pressure vessel made of a composite material according to the present invention is constituted of an inner tube (2) formed of a fiber-reinforced resin material, a rigid attaching member (10 or 30) which is fit into at least one of the two axial ends (4 and 5) of the inner tube (2) and is provided with at least one protrusion (20 or 42) made of a fibrous material, and an outer tube (3) formed by winding a resin-impregnated fibrous material (50) around the peripheries of both the inner tube and the attaching member while reversing the direction of winding of the fibrous material by hooking it on said protrusion. Each of the sections where the attaching member (10 or 30) is fit into the axial end (4 or 5) of the inner tube (2) is designed to involve at least one pair of mutually abutting faces (7 and 22; 8 and 23; or 9 and 36), and the diameter of the periphery of an area ranging from the abutting face (23 or 36) of the attaching member (10 or 30) to at least a section provided with the protrusion (20 or 42) is adjusted to be nearly equal to the outer diameter of the inner tube (2).

    摘要: A seismic source (10) is described which drives one or more jets of high velocity water into an underwater environment and then abruptly terminates the jets. The momentum of the free jet columns generate vapor cavities in the water away from the housing (12) of the source which cavities collapse coherently to generate the seismic signal. A piston (22) and a valve sleeve (38) are slidably mounted in a cylinder (14) in the housing. The piston seals off a volume of gas on its rearward side. The forward side of the piston defines one surface of a chamber (24). The chamber receives high pressure water from an inlet. In its rearward position the valve sleeve seals a set of jet apertures (60) in the side of the cylinder. In its forward position the valve sleeve opens the apertures, exposing the chamber interior to the exterior underwater environment. With the valve sleeve in its rearward position with the apertures sealed, the high pressure water entering the chamber (24) moves the piston to its rearward position and compresses the gas. The sleeve (38) is hydraulically actuated upon command to abruptly open the jet apertures, enabling the piston to move forwardly under the pressure of the compressed gas, driving the water through the jet apertures so as to form the jets. The piston (22) enters the interior (40) of the sleeve (38) near the forward end of its stroke and, concurrently, abruptly terminates the jets. To re-arm the source, the sleeve is actuated to close the jet openings whereupon the high pressure water resets the piston (22). Upon the next command, the valve sleeve (38) is again actuated to open the apertures and the next seismic signal is generated.

    摘要: A combination of a cylinder 62 of an internal combustion engine and a piston ring 40 for sliding an inner periphery of the cylinder, wherein at least a sliding face of the cylinder is composed of an aluminum alloy including 8 mass% to 22 mass% of Si and at least one or more particles selected from the group consisting of Si, Al 2 O 3 and SiO 2 particles each having a diameter of 3 µm or more, and at least an outer periphery of the piston ring is coated with a hard carbon coating 14 composed only of hydrogen and carbon.
