Definitions
- a pneumo-hydraulic converter with a reciprocating double piston which connects a compressed air reservoir with a hydraulic circuit with the best possible efficiency, such that
- Energy in the storage f Hessen can (charging) or can be drawn from the storage (discharging).
- the purpose of the invention is to achieve good efficiency while increasing the clock frequency.
- This heat exchanger can either run with the reciprocating piston set or remain fixed.
- the moving heat exchanger requires about a third fewer sliding seals and, in addition, the tubular bundle significantly increases the kink and buckling resistance of the piston set, the description will be limited to the representation of the converter with the moving heat exchanger: the desired increase in the clock frequency forces a radical Dead space-reducing workspace arrangement which causes high buckling forces, which leads to buckling strength extremely important constructive factor, which must also be taken into account in the arrangement of the valves.
- the valve sets each side must - consisting j in each case from high-pressure valve, exchange valve and low-pressure valve forced to be controlled, said low pressure valve may be coupled in their movement under certain conditions, exchange and.
- the design of these valves must also meet the topological requirements of the heat exchanger
- FIG. 1 shows a longitudinal section through the axis of the four cylindrical
- FIG. 2 shows a section transverse to the axis of FIG. l through the high-pressure chamber and through the heat exchanger tube bundle, and finally
- FIG. 3 illustrates the same section as FIG. 2, but with bridged bundle tubes.
- the converter in its high-pressure version consists of three coaxial cylindrical tube sections of approximately the same length, the upstream pressure tube (1) surrounding the upstream pressure piston (2) having a much larger diameter than the two high-pressure chamber tubes (3a / 3b) arranged symmetrically with respect to the upstream pressure tube (1) ), which also contain the longitudinally symmetrical high pressure pistons Ua / 4b). Since the moving parts as well as the fixed parts are mirror-symmetrical with respect to their long center, the upstream pressure pipe (1) is connected via valve flanges (5a / 5b) to the two screwed-in high-pressure chamber pipes (3a / 3b), each of which is attached by means of screw caps ( 6a / 6b ) attached connection cover (7a / 7b) must be completed.
- the outside world communicates with the pre-pressure spaces (lla / llb) via the low pressure valves (13a / 13b) and the air reservoir (K) can the air high pressure spaces (lOa / lOb) via the high pressure valves (15a / 15b) act on, which are supplied from the air reservoir (U) through the supply lines (I6a / l6b) via the connections (17a / 17b).
- FIG. 1 A possible configuration of the pilot control by means of hydraulic loading is shown in FIG. 1 shown on the high pressure valves (15a / 15b), the pressure chambers (I8a / 18b) each from the one
- Pressure source (19) connected electrical 2-way
- Pilot valves (20a / 20b) are either released or pressurized, thereby moving the valve pistons (21a / 21b), which are connected to the high-pressure valves (15a / l5b) via the rods (22a / 22b) with nuts (23a / 23b) .
- Similar devices can also be provided for the exchange valves (12a / 12b) and the low pressure valves (13a / 13b), only their actuating rods (24a / 24b) and (25a / 25b) being shown here.
- a wiring option of the converter is shown, with supply lines (27a / 27b) to a -V-way valve (28), which is a variable hydrostatic unit (29) with a flywheel ( 30 ) and an electric motor / generator (31) acted upon.
- the exchange circuit begins with the feed pump (32), which the exchange liquid through the external Insert exchanger (33) via the connection (34b) in the connection cover (7b) and via the feed pipe (35b) into the pipe rod (8). Since this pipe rod (8) is closed in the plane of the pre-pressure piston (2) by a conical stopper (36), the exchange liquid is pressed back through the annular space between the feed pipe (35b) and the pipe rod (8) to the high-pressure piston, in which
- Radial bores (37b) are fed to the exchanger bundle tubes (38), thus also the high-pressure piston (4a) - via the radial bores (37a) the tube rod (8) is in turn reached; the circuit back to the feed pump (32) is closed via the feed pipe (35a) and the connection (34a).
- the exchanger seals (41a / 41b) and (42a / 42b) are loaded with a full pressure difference throughout the piston movement: this is the actual technological challenge of the concept, especially if the tube bundle design is designed to bypass the bundle tube (43) in order to increase the kink resistance and heat transfer (43). 3 provides. Only the sliding seal ( 44) of the upstream pressure piston (2) is spared from the high pressures, since it is only exposed to the upstream pressure. The remaining seals, not specified, are only subjected to static or short-stroke loads.
- topological configuration shown is part of the invention and fits particularly well with the described, repetitive thermodynamic process, especially since the pressure chamber and exchanger arrangement selected enables the dead space-free shuttle valve design, with which the concept of conversion with the highest possible Efficiency stands and falls.
- the 4-way changeover valve (28) must either be automatically synchronized (by the pressure peak at the stop) or by means of a proximity switch with the converter stroke; for simple compression tasks (e.g. for cooling circuits), the compressor can also be designed without a pre-pressure cylinder: the shell-and-tube heat exchanger can be either fixed or rotating, since there are no buckling forces.
