摘要： The invention relates to a hydraulic accumulator, especially a hydraulic damper, comprising a connecting piece (18) for producing a fluidic connection between the interior (16) of said hydraulic accumulator and at least two fluid connecting lines (20, 22) that are part of a fitting (24) when assembled, whereby the connecting piece (18) is connected to the fitting (24). The connecting piece (18) is provided with at least one annular channel (26) in the outer periphery thereof in such a way that, once assembled, the connecting section (28) of the connecting piece (18) leading to the interior (16) of the hydraulic accumulator is in fluidic connection in the fitting (24) with fluid connecting line (22) by means of the annular channel. This makes it possible to obtain a compact construction of the described array and to avoid the disadvantages of long lines.

摘要： The invention relates to a pressure means accumulator (31) for vehicle brake systems with automatic brake control. The inventive pressure means accumulator has a housing (32) with two pressure means connections (33, 34) and an accumulator chamber (35) interconnecting them, an elastic membrane (41) delimiting said accumulator chamber (35), said membrane being fixed in the housing (32) on the edges, and an air-permeable support body (42), which is accommodated in the housing (32) and which has a support surface (43) for supporting the membrane (41). According to the invention, a large area of the support surface (43) is drawn deeply into the support body (42) and the membrane (41) is guided along on the support surface (43) in its non-extended state in order to improve the freeing of the accumulator volume and hereby improve the dynamics for the build-up of pressure when the traction control system is in operation or during regulation of driving dynamics. The support surface (43) is preferably shaped by the inner contour of a pot-shaped recess (48) in the support body (42).

摘要： Pulsation damper for damping low-frequency gas pulses emanating from a compressor of the Root blower type. In a vessel, an inlet and an outlet are arranged, at least one of which is designed as a diffuser. In order to increase the strength of the diffuser, it is proposed to remove parts from pipe material of relatively high thickness, so that windows are formed. These windows, with relatively large openings, are then covered with plates of perforated material. These are preferably situated on the upstream side of the pipe.

摘要： An extrusion apparatus and method, and a tubular product and a pipe made of several different materials. The extrusion apparatus according to the invention comprises at least one stator (1, 6, 10), at least one rotor (2, 2a, 2b), and at least one annular feed gap (3) situated between the stator (1, 6, 10) and the rotor (2, 2a, 2b). The diameter of the feed gap (3) decreases at least partly continuously in the direction of flow of the plastic material to be extruded, and its diameter also increases continuously at least at a section of its length in the aforementioned direction of flow. With such a construction, the pressure acting on the structure of the extrusion apparatus can be considerably balanced, i.e. the apparatus can be made more durable. The invention also relates to a tubular product and a pipe made of several different materials.

摘要： In order to absorb disturbing pressure pulsations in a high pressure hydraulic system, the transport pipe (15) between source (10) and consumer is cut in at least one place and a damper (16) is mounted. The damper comprises at least one damper pipe (17, 18), having a larger diameter than the transport pipe (15), without normally exceeding an inner diameter of 70 mm. If two or more parallel damper pipes are used, these are connected by means of a part (19) of the long intervening pipe, so that a compact unit is obtained, suited to local conditions.

摘要： A pulsation dampening device includes a body having an upper connection end and a lower connection end, each connection end adapted to connect the body to connectors for a drill string pipe segment. Flow restriction is provided within an internal flow path extending axially through the body and is configured to reduce pumped fluid pressure pulses. The flow restriction is provided by a combination of one or more orifice(s) having sharp edges and restricting fluid flow within the internal flow path, optionally coupled with relief feature(s) gradually increasing or decreasing a cross-section of the internal flow path, or by an orifice device. The flow restriction may operate unidirectionally or bidirectionally relative to predominant fluid flow direction in attenuating pressure pulses. Spacing between the orifice(s) and the relief feature(s) is based on a waveform of pulsation energy for pressure pulsations to be attenuated.
