Combined relief and surge protection device for compressible operating medium containers of hydrodynamic machines

Abstract

The provider network that interconnects user networks includes a plurality of edge routers. At least one of the plurality of edge routers includes an obtaining unit for obtaining information of a packet transferred by the edge router itself, a creating unit for creating a flow list in which flow information of packets transferred from the user network side to the provider network side is registered based on the packet information, a monitoring unit for monitoring a traffic state of a flow of each packet registered in the flow list based on information of packets transferred from the provider network to the user network, and a notifying unit for notifying the traffic state of the flow registered in the flow list to a maintenance engineer.

Description

technical field [0001] The invention relates to a combined decompression and splash protection device for a working medium container that can be placed under pressure in a working medium supply system of a hydraulic machine, and also relates to a working medium supply system for a hydraulic machine. Background technique [0002] Hydrodynamic machines in the form of hydrodynamic couplings, hydrodynamic reducers or hydrodynamic speed / torque converters are known from the prior art in various embodiments. All have in common the use of fluid forces to achieve a defined function. These hydraulic components can be switched on and off by filling and emptying the working fluid of the bladed working circuit when used in motor vehicles or in machines with intensive alternating work. In particular a hydrodynamic retarder - which consists of a primary wheel acting as a rotor impeller and a preferably stationary secondary wheel acting as a stator - will be injected and exhausted by gener...

Problems solved by technology

However, in this case, on the one hand, due to the temperature rise, more oil will be returned to the working medium container than before, and on the other hand, due to the direct contact of the working medium with air, air will enter the liquid and lead to undesired foaming, especially the formation of bubbles

This leads, on the one hand, to a certain degree of formation of a so-called air cushion in the working medium container during several successive braking operations, which in turn leads to the fact that only reductions can be achieved with equal loading of the working medium levels. small braking effect

On the other hand, it is precisely in the case of several successive braking processes - characterized by the necessary alternation between emptying and filling of the working chamber - that the formation of air bubbles is very unfavorable, because the influx of air increases the number of air bubbles and This also allows the working medium-air mixture to reach the depressurization system, which can lead to a complete interruption of the function in certain cases, especially if the same line connection is used for depressurization as for pressurization
