摘要： The invention relates to a valve, especially a pressure control valve, comprising a housing (10) with at least one pump connection (P), useful connection (A) and tank connection (T). A piston (16) which can be controlled by a magnet armature (26) is guided inside the housing (10) of the valve. The valve is provided with a hydraulic damping device (34) which has a damping chamber (36) which is fluidically connected to the useful connection (A) by means of a throttle (38), and the pump connection (P) or the tank connection (T) is selectively joined to the useful connection (A) via a connecting line (40) according to the position of the piston (16). The invention thus improves upon known control valves so that said control valves remain stable in terms of behaviour, especially with regard to permanent oscillations.

摘要： The invention relates to a fluid cooling device with a cooling, filtering and pumping device that is combined in a building unit (10). Fluid that is conveyed by the pumping device (16) can be filtered in a fluid circuit (18) by means of the filtering device (14) and can be cooled in said circuit by means of the cooling device (12). The filtering device (14) is provided with at least one filter element (24) that can be exchanged when the filter device is clogged. The aim of the invention is to improve the known fluid cooling device. A controllable holdback unit (26) is provided in the fluid circuit (18) for an exchange of the respective filter element (24). The filtering device (14) can be separated from the pumping device (16) by means of said holdback device in such a way that the cooling device (12) is still supplied with the fluid to be cooled. The filter element can be exchanged without entailing further difficulties even when the downstream supply of lubricating oil is not stopped.

摘要： The heating system uses a heating circuit (HL) containing a number of heating devices (H1,..H3), selectively coupled to each of a number of parallel cooling circuits (KL1,...KL3). These are used for the fluid-cooled electrical devices of the train, e.g. the traction motors, the current regulators, or the transformers, each cooling circuit used for cooling devices at the same temp level. A mixer may be used in the heating circuit to provide control over the heating power. When the fluids in the cooling and heating circuits can't be mixed, the cooling circuits may be coupled thermodynamically to the heating circuit via a heat exchanger, with the selective coupling to each cooling circuit effected via switching valves.

摘要： An actuator (10), pref. a double-acting hydraulic cylinder, is connected by delivery (24) and return (26) lines to a switching valve (28). Two releasable non-return valves (30, 32) are connected in parallel to the other non-return valves. The control line (34) of the first releasable non-return valve (30) is connected to the outlet port (44) of the second releasable non-return valve.

摘要： 2. The valve is, in particular, a two-way flow control valve which has means for freely setting the quantity of a throughflow and means for detecting the pressure prevailing at the inlet of the valve. … This prevailing pressure acts at least with one force component on an actuator against the effective force of an accumulator and against the effective force of the pressure prevailing at the outlet of the valve. The quantity of the throughflow can be regulated at the outlet of the valve using the actuator. … …
