Abstract:
A displacer unit with a valve plate body is disclosed. The displacer unit having at least one displacer space which is arranged in a cylindrical drum rotating about an axis of rotation and which can be connected to an inlet connection and an outlet connection by a control surface. The control surface is formed on a valve plate body which is provided with a first control opening, which is connected to the inlet connection, and with a second control opening, which is connected to the outlet connection. The first control opening and the second control opening are spaced apart radially, where the displacer space can be connected to the first control opening by a first connecting passage and to the second control opening by a second connecting passage. The connecting passages are provided with a respective mechanical face seal for sealing relative to the control openings.
Abstract:
The invention relates to a compressor (1) for gaseous and/or cryogenically liquefied media comprising a first compressor piston (6) and a second compressor piston (7), which are operatively connected to an eccentric shaft (2), wherein the second compressor piston (7) is arranged substantially opposite to the first compressor piston (6) relative to the eccentric shaft (2). To solve the object of providing such a compressor with a small space requirement and low construction costs, it is proposed according to the invention for the compressor (1) to be embodied as an oscillating piston-type compressor, wherein the first compressor piston (6) is arranged on an eccentric ring (4), which is effectively connected to the eccentric shaft (2) and wherein the second compressor piston (7) is fastened to a pivot lug (8), which is effectively connected to the eccentric ring (4).
Abstract:
The invention relates to a compressor for cryogenic media comprising at least one compressor cylinder in which a compressor piston is arranged, wherein the compressor piston interacts with a crankshaft by means of a connecting rod. To solve the object of attaining a secure operation and of attaining a long service life of the compressor by means of low production efforts, it is proposed according to the invention that the compressor piston is embodied as an oscillating piston.
Abstract:
A method and device for compressing a gaseous medium, specifically hydrogen, is disclosed. Compression of the gaseous medium takes place by way of a fluid, where a fluid is used in which the gaseous medium is not soluble and/or can be separated residue-free from the gaseous medium. An ionic fluid, a high-boiling hydraulic oil, or a fluid which has a very low vapor pressure is used as the fluid.
Abstract:
The invention relates to a method for filling up a storage tank (e.g., a vehicle tank) (20) with a gaseous, pressurized medium, in particular in the form of hydrogen, in which a supply tank system (2) for storing the hydrogen is connected with the storage tank (20) to be filled by way of a tank feed line (3) and a fueling valve (4), wherein, prior to filling up the storage tank (20) with aforesaid medium with the fueling valve (4) closed, a flow of the medium for cooling the tank feed line (3) is guided through the tank feed line (3) at a predefinable target temperature, and removed from the tank feed line (3) through a line (5) that branches away upstream from the fueling valve (4). In addition, the invention relates to a fueling facility (1) for filling up a storage tank (20).
Abstract:
A multistage piston compressor for a gaseous or cryogenically liquefied medium with at least two compressor stages, which operatively interact with a shared drive train for purposes of joint powering, wherein each compressor stage exhibits a piston that is mechanically connected with the drive train, and arranged in a compressor cylinder so that it can longitudinally shift.
Abstract:
Described is a method for filling a storage container with a gaseous, pressurized medium, preferably with gaseous, pressurized hydrogen.According to the invention, a determination of the internal storage container pressure takes place at the onset of the filling process by means of a pressure test impact and a filling process with time-controlled pressure increase up to the desired internal storage container pressure takes place subsequently as a function of the established internal storage container pressure.
Abstract:
An engine having at least one displacer cylinder in which a liquid, in particular an ionic liquid, is arranged and which can be connected to a feed passage and a discharge passage for a medium, is disclosed. The liquid is operatively connected to a displacer device. The displacer cylinder is arranged in a cylindrical drum, rotatably mounted about an axis of rotation, at an angle to the axis of rotation of the cylindrical drum. In an embodiment, the displacer cylinder is arranged perpendicularly to the axis of rotation of the cylindrical drum, and the displacer cylinder is designed as a radial bore arranged in the cylindrical drum.
Abstract:
A yarn twisting and winding apparatus is disclosed which is adapted to produce a yarn ball, and which includes a yarn support spindle (12) and surrounding flyer (19). The flyer is rotatable about a central axis (15), and the yarn support spindle is mounted so that its axis (12') intersects the central axis. Also, the spindle (12) is rotated about the central axis (15), as well as its own axis (12') during the winding operation. A yarn delivery roll (4) is mounted coaxially about the central axis, and so that the yarn is adapted to advance to the flyer, around the yarn delivery roll, back to the flyer, and then to the yarn support spindle to form a yarn ball.
