摘要： Regarding a sliding structure for an internal combustion engine of the present invention, a cylinder has a plurality of recesses formed in a stroke center region. Piston rings are configured to have inclined surfaces formed on an outer circumferential surface thereof, and a lubricating oil flows into a gap between the inner wall surface and the outer circumferential surface that relatively move via the inclined surfaces, thereby enabling fluid lubrication. At any RPM equal to or greater than an RPM for an idling operation of the internal combustion engine, a friction coefficient (hereafter, a center friction coefficient) at a place of the stroke center region through which the piston rings pass at the highest speed is set to be less than a center friction coefficient when it is assumed that the recesses are not formed in the stroke center region. On the other hand, at the RPM, a friction coefficient (hereafter, an outside friction coefficient) when the piston rings pass through any place in an outside region that is outside the stroke center region is set to be less than an outside friction coefficient when it is assumed that the plurality of recesses are formed in the outside region. As a result, it is possible to achieve further improved low fuel efficiency for the dimple liner technique.

摘要： A composite cylinder constructed from a cylindrical liner (12) having an outer surface (18) which is dome shaped adjacent each end. A plurality of layers (30) of resin impregnated carbon filaments are wound on the outer surface (18) of the liner (19) and over the dome shaped portions. Preferably the filaments are helically wound and are wound at an angle with respect to the access of the cylindrical liner (12) such that radial stress as applied during operation will not tend to displace the filaments wound over the dome shaped portions of the liner (12). The composite cylinder is useful as an integral part of a hydraulic actuator used to position flight control surface on aircraft.

摘要： A fastening device for actuating cylinders with longitudinal stringers (2, 3) extending axially along a cylinder tube (1). A fastening yoke, e.g. comprising two halves (6a, 6b), is clampable with the aid of at least one clamping screw (8r) for fixing it in a desired axial position along the cylinder tube. In accordance with the invention the opposing clamping portions (6ar, 6br) of the fastening yoke act on two intermediate clamping blocks (10ar, 10b) which are thus pivoted in opposite directions, so that clamping is achieved exclusively against the inner and outer side portions (2i, 2y and 3i, 3y), whereby internal deformation of the cylinder tube (1) is prevented.

摘要： A cylinder (10) having a radially movable or pivoting rod (22) slidably received in a floating gland (40) disposed in a cavity or recess (42) in an end cap (12) of the cylinder. Preferably, seals (68,58,80,82) are provided between the rod (22), gland (40) and recess (42).
Hence, the rod and gland can move radially while a fluid tight seal is maintained between the atmosphere and the interior of the cylinder to retain pressurized fluid therein.
Preferably, to facilitate radial movement of the rod (22) and hence the gland (40) in the recess (42), the forces on opposed faces of the gland (40) are equalized by an appropriate arrangement of seals to define equal surface areas on the opposed faces both of which communicate (88) with the interior of the cylinder.

摘要： Une source sismique (10) actionne un ou plusieurs jets d'eau a grande vitesse en milieu aquatique et arrete soudainement les jets. La force de ces colonnes d'eau creent des poches de vapeur dans l'eau loin de l'enveloppe (12) de la source, cavites qui se resorbent de maniere coherente pour produire le signal sismique. Un piston (22) et une soupape en forme de manchon (38) sont montes coulissants dans un cylindre (14). Le piston enferme sur sa partie arriere un volume de gaz. La partie avant du piston definit une surface d'une chambre (24). La chambre recoit de l'eau haute pression par une admission. En position arriere, la soupape-manchon ferme hermetiquement un ensemble d'orifices de jets (60) sur le cote du cylindre. En position avant la soupape-manchon ouvre les orifices exposant l'interieur de la chambre au milieu aquatique. Avec la soupape-manchon en position arriere, les orifices etant fermes, l'eau haute pression qui entre dans la chambre (24) deplace le piston en position arriere et comprime le gaz. Le manchon (38) est actionne hydrauliquement sur commande pour ouvrir brusquement les orifices de jets, permettant au piston de se deplacer vers l'avant sous la pression du gaz comprime, chassant l'eau au travers des orifices de jets pour produire les jets. Le piston (22) penetre a l'interieur (40) du manchon (38) pres de l'extremite de sa course avant et, conjointement, arrete brusquement les jets. Pour rearmer la source, le manchon est actionne pour fermer les orifices des jets, puis l'eau haute pression remet le piston (22) en place. Lors de la commande suivante, la soupape-manchon (38) est de nouveau actionnee pour ouvrir les orifices et un nouveau signal sismique se produit.
