Abstract: The invention relates to a method for monitoring the gas prefill pressure in hydraulic accumulators (1). In said method, after the pressure supply to the oil side (5) of the accumulator has been interrupted and the contents of the tank (41) have been emptied, the current gas temperature and the current gas pressure are determined, once the temperature has equalised. The data relating thereto is telemetrically transmitted to an evaluation unit (51) which is spatially located at a distance, in order to calculate an actual value of the gas prefill pressure which corresponds to a reference temperature.

Abstract: The invention relates to a pressure means storage device, comprising a housing (1), the inside of which is divided into two chambers (3, 4) by a media separation element (2). The first chamber (3) is filled with a gas and the second chamber (4) is filled with a liquid. A bottom valve (6) which allows the second chamber (4) to be filled with the liquid and prevents said second chamber (4) from being completely emptied is provided in a hydraulic connection (5), the closing body (7, 40) of said valve being activated by the media separation element (2). According to the invention, the closing body (7, 40) can be moved by means of the media separation element (2 or 16) into a position in which it performs the function of a hydraulic piston. This prevents the bottom valve from being damaged and any unwanted leakage of the liquid, hereby considerably increasing the functional reliability.

Abstract: For sealing between two opposed surfaces of two machine elements (1, 2) a combination seal is provided to be fitted into an open groove (3) in one of the machine elements (2). The seal comprises an elastomeric expansion ring (4, 5) at the bottom of the groove (3), an intermediate ring (6) made of a viscous-elastic material, e.g. PTFE and having a sealing surface (6b) to contact the mating machine element (2), and an elastomeric outer ring (8) fitted into a separate groove (7) in the sealing surface (6b) of the intermediate ring. Especially in cases where the seal is to separate fluid and gas an improved distribution of the contact pressure at the sealing surface (6b) and also an effective hydrodynamic relief of the outer ring (8) preventing its exposure to injurious pressures and subsequent damage is obtained by designing the intermediate ring (6) at the ends of the sealing surface (6b) with comparatively sharp corners (16, 17), the parts of the sealing surface between these corners and the separate groove (7) forming conical faces (14, 15) which at a narrow slit angle converge towards the separate groove (7). The intermediate ring may also be biassed by the two expansion rings (4, 5) placed on each side of the separate groove (7).

Abstract: A hydraulic actuator (1a, 1b), particularly of the shock absorbing and/or damping type, comprising a piston (2) that is accommodated so that it can slide hermetically in a hollow cylinder (3) so as to divide the internal volume of the hollow cylinder (3) into two chambers (4, 5) mutually separated by the head (6) of the piston (2). The two chambers (4, 5) are connectable separately, respectively by means of at least one delivery duct (17) and at least one discharge duct (18), to a first circuit adapted to feed under pressure a first fluid into one of them with consequent emptying of the other one for the extension or compression movement of the piston (2) with respect to the hollow cylinder (3). The hydraulic actuator comprises a first movable element (7) that is accommodated so that it can slide hermetically in a longitudinal cavity (8) defined inside the stem (9) of the piston (2) so as to divide the longitudinal cavity (8) into two portions (10, 1) with the first one connected to one of the two chambers (4, 5) and with the second one connectable to a second circuit adapted to feed under pressure a second fluid into the second portion (11). The second fluid has a coefficient of compressibility and a nominal pressure greater than those of the first fluid so as to act as a shock absorber and/or damper in case of sudden peaks of pressure in the chamber (4, 5) connected to the first portion (10) of the longitudinal cavity (8) defined inside the stem (9) of the piston (2).
