- the expansion machine can for example for
- Waste heat utilization of an internal combustion engine can be used.
- the expansion machine comprises a transmission with an output shaft and a shaft seal cooperating with the output shaft.
- the expansion machine has an inflow region and an outflow region and, during operation, flows through a working medium, wherein compressed working medium flows out of the outflow region into the inflow region and relaxed working medium.
- Shaft sealing ring separates a gear chamber or valve chamber filled with working medium from an ambient space or from a further machine, for example from a generator.
- the expansion machine is operated in overpressure, that is, the relaxed working fluid has a pressure that is above atmospheric pressure.
- the sealing lip is then arranged in such a way to the output shaft, that an overpressure in the expansion machine to the ambient space, which is under atmospheric pressure, reliable
- the expansion machine according to the invention with a shaft seal and a valve in contrast, has the advantage that it can be operated both in overpressure even in vacuum operation without leakage and the shaft seal achieved a good sealing effect in all operating conditions.
- the expansion machine according to the invention thus has a much wider range of operating conditions in which it can be used without leakage.
- the expansion machine comprises an output shaft and a shaft seal cooperating with the output shaft.
- Expansion machine has an inflow and an outflow area. In operation, the expansion machine is flowed through by a working medium, wherein compressed in operation of the expansion machine
- Working fluid flows into the inflow and relaxed working fluid from the outflow.
- the shaft seal separates one with working fluid filled valve space from an ambient space.
- a valve is arranged, and the pressure in the valve chamber is regulated by the valve.
- the pressure acting on the shaft sealing ring on the side of the expansion machine can be regulated.
- the pressure on the shaft sealing ring on the side of the expansion machine is always at least as great as on the side to the environment or to the
- the expansion machine comprises a housing, wherein the valve is arranged in the housing.
- the valve does not require its own housing, but can be inexpensive and
- inflow is hydraulically connected to the valve chamber through a throttle.
- valve chamber can be controlled by the valve to the pressure level of the inflow, this
- Pressure level is higher than the pressure level of the surrounding space; This achieves a good sealing effect of the shaft seal.
- valve chamber is not connected to the inflow region but to a region that is between inflow and outflow
- the valve comprises an inlet channel, an outlet channel, and a closing body.
- the closing body is preferably spherical.
- the closing body cooperates with a valve seat.
- the inlet channel opens into the valve chamber or leads out of this.
- the closing body closes when applied to the valve seat a hydraulic
- the outlet channel is at least indirectly with the
- Expansion machine is. This minimizes stress on the shaft seal when the valve is open.
- the valve comprises a control room and an opening into the control room
- Control channel This allows the valve to be pneumatically or hydraulically controlled or even controlled.
- Control variable for the valve can be used. Furthermore, the control with atmospheric pressure or with the pressure of the ambient space is very cost-effective, since a volume having a corresponding pressure level, anyway in the expansion machine or its attachments or just in the environment is present.
- the valve comprises a membrane, and the control chamber adjoins the membrane. This allows the control room Media-tight, in particular to the inlet channel and the outlet channel to be separated.
- the membrane is made of a metal, in particular of a thin metal, or of an elastomer. This is the membrane
- Inlet channel to outlet channel accordingly also has a sufficiently large cross-section with the valve open.
- the membrane acts on her the
- membrane and closing body together.
- the geometries and materials of membrane and closing body can be selected as best as possible with regard to their functions: the membrane is comparatively elastic and the closing body is wear-resistant and comparatively stiff.
- the membrane cooperates with the interposition of an auxiliary piston with the closing body, wherein the auxiliary piston is preferably longitudinally movably guided in a guide sleeve.
- the auxiliary piston has the function of performing the longitudinal movement during opening and closing of the valve with as little friction as possible, for example in cooperation with the guide sleeve.
- the power transmission between the auxiliary piston and closing body can be designed so that the closing body during opening and closing of the valve.
- an annular chamber is formed at least partially surrounding the inlet channel radially.
- the outlet channel opens into the annular chamber, wherein the valve seat is arranged between the inlet channel and the annular chamber.
- the pressures from the outlet channel or the annular chamber and from the inlet channel act in the same direction on the closing body. If the outlet channel is under a lower pressure than atmospheric pressure, then the closing body is loaded with a comparatively small resulting hydraulic force by the working medium for this operating state. The closing body is therefore against the valve seat pressed. Since the valve seat is formed between the annular chamber and the inlet channel, so can also be set over the width of the valve seat, a throttle length for the operating state of the opened valve.
- the closing body is a membrane, preferably of one
- the membrane can be simple, for example, disc-shaped, constructed and is therefore inexpensive to use.
- a control chamber is also formed here on the opposite side of the valve seat of the membrane, which opens into a control channel.
- the control room can thus be connected via the control channel to a volume, the one
- control space between the membrane and a lid is formed.
- the lid also preferably braces the membrane at its periphery, for example by pressing the membrane against the housing of the valve or the expansion machine.
- the membrane is fixed on the circumference within the valve. The opening and closing of the valve thus takes place by a movement of the non-strained surfaces of the membrane.
- control channel is formed in the lid, wherein the control channel is preferably hydraulically connected at its end opposite the control room end with the surrounding space or with the atmosphere.
- control channel can be produced inexpensively by a simple hole in the lid.
- control channel can alternatively also save space through a common housing of expansion machine or valve and
- the expansion machine according to the invention is arranged in a waste heat recovery system, in particular an internal combustion engine.
- the waste heat recovery system comprises in the flow direction of the working medium, a pump, an evaporator, the expansion machine and a condenser.
- the outlet channel is hydraulically connected at least indirectly to the condenser.
- Outflow area of the expansion machine is usually hydraulically connected to the condenser and thus has the same pressure as the condenser.
- the outlet channel is then connected to this already existing pressure level.
- the waste heat recovery system is preferably not operated at a single operating point, but at very different operating points, since the internal combustion engine is operated at different operating points. This makes it very beneficial for the overall efficiency of the waste heat recovery system when the expansion machine can run in both positive pressure and negative pressure modes.
- the expansion machine according to the invention is therefore particularly suitable for this purpose.
