摘要： A frictionless hydraulic damper including a cylinder having end walls mounting the opposite ends of a shaft with a clearance in labyrinth seals, bellows seals between each end wall and the portions of the shaft extending beyond each end wall, a piston head on the shaft within the cylinder, hydraulic fluid in the cylinder and in both bellows seals, an orifice construction located relative to the piston head for permitting flow of hydraulic fluid past the piston head to produce damping, and a conduit in the shaft for effecting communication between the two bellows. The damper as described above also functions as a snubber by including a valve construction which selectively closes the orifice construction.

摘要： A hydraulic braking device for a load subjected to shocks and vibrations for the stabilization of loads in thermal or nuclear generating stations.The braking device has a cylinder 1 in which there slides the piston 4 of a rod 7 bearing two flap valves 18 and 19 to brake the passage at high speed of hydraulic fluid from one chamber 15 or 16 to the other. These valves communicate with a reservoir 17, pressurized by springs 31 to 34 and accumulate the expansions of the fluid. A secondary rod 29 which has displacements with respect to rod 7 which are reduced relative to the displacement of piston of reservoir 27 with respect to this rod 7 serves as a leak indicator.Application to the stabilization of loads such as high-temperature steam conduits in thermal or nuclear generating stations.

摘要： A gas spring, particularly adapted as a lifting means for hatch backs or trunk lids of motor vehicles, comprises a piston rod acting as a displacement piston, a housing cylinder containing a compressed gas, a guide piston near one end of the piston rod and in slidable relationship with the interior of the cylinder housing, characterized in that the piston rod is provided with an extension projecting beyond the guide piston, the closed end of the cylinder housing having a complementary receptacle for the piston rod extension, whereby when the piston rod is fully retracted into the cylinder housing, the extension enters the complementary space in the housing in a sealing manner, a valve being provided to permit the escape of fluid from the space as the extension passes thereinto, whereby the force acting to extend the piston rod is reduced to zero or nearly zero in the vicinity of the fully retracted position of the piston rod.

摘要： A telescopic gas spring comprises a cylinder closed at one end, a piston slidable in the cylinder and a piston rod carrying the piston and extending sealingly through the other end of the cylinder. An auxiliary spring is disposed at the closed end of the cylinder and comes into operation as the piston approaches a position of full compression, to provide additional resistance to further compression of the gas spring. The auxiliary spring may be a coil spring or a gas spring.

摘要： A hydraulic mitigator comprises a relatively massive hollow housing having two coaxial bores, the second bore being larger than the first. A shaft partially extending outside the housing rides in the first bore while a piston which is connected to the shaft rides exclusively within the second bore. The larger bore is filled with a fluid of a known density and a space is provided between the bore and the outer rim of the piston to enable the piston to be propelled through the fluid. The portion of the shaft which extends outside the housing is provided with an enlarged plate which is intended to be struck by the projectile. Any force directed at the plate will be only partially transmitted to the housing, the remainder being dissipated in propelling the piston through the fluid. Thus by properly selecting the density of the fluid and the size of the space between the piston and the bore, one can impose a predetermined deceleration force to the projectile. If the mitigator is spinning at the moment of impact such a spin can be partially transmitted to the projectile. This is accomplished by providing a pin and groove coupling means between the housing and the shaft in order to impart some of the angular acceleration force of the massive housing to the relatively lightweight shaft.

摘要： A shock absorber which comprises a working cylinder, a piston arranged to slide in the cylinder and main fluid control means controlling flow of fluid from one side of the piston to the other. Subsidiary fluid control means are provided which are arranged to impose a threshold resistance to movement of the piston with respect to the cylinder in at least one direction, and to reduce or eliminate the threshold resistance after an initial movement of the piston with respect to the cylinder.
