摘要:
The invention starts with a volume flow control valve (36, 38) with a flow restrictor (48, 54) that can be displaced axially in a housing (40, 44), via which the volume flow can be diverted. It is proposed that the flow restrictor (48, 54) have a diverting body (54) and the force generated by the diversion at the diverting body (54) be used to adjust the flow restrictor (48, 54).

A closure for a tank, in particular a fuel tank for a motor vehicle or the like, that has a tank filling pipe which can be closed with a closure flap, is described. The closure flap has a locking device with which it can be locked and unlocked and is also connected by a hinge or the like, so that it can move into the interior of the tank filling pipe. The locking device is located completely beneath the closure flap so that the closure flap can be locked and unlocked. Thus the locking device is not accessible from the outside, so it cannot be damaged or operated by an unauthorized party. The tank filling pipe can also be sealed airtight by the closure flap or by a closure valve arranged in the tank filling pipe.

The invention relates to a system to regulate the heat balance of a vehicle, with a heat cycle that dissipates engine heat, which features a cooling circuit (38) and a heating circuit (36), through which circuits a coolant can flow, and with at least one component (20) of the vehicle producing waste heat, wherein a system is provided with which the waste heat of at least one component of the vehicle can be transferred to the heat cycle.
摘要:
A cooling circuit for an internal combustion engine includes a first coolant circuit and a second coolant circuit, the cooling circuit being able to be operated by a distributor so that the internal combustion engine reaches its operating temperature as quickly as possible, and a heat exchanger used to heat the vehicle interior is operational as quickly as possible. The return channel from the second coolant circuit is connectable to either the return channel or the flow channel of the first coolant circuit.

An electric machine, particularly a generator for motor vehicles, includes a housing and a casing enclosing the housing concentrically, the casing, together with the housing, bounding an annular space that is sealed in a fluid-tight manner and is connected to a coolant outflow and a coolant inflow. To achieve a uniform circumflow of the housing with sufficient cooling capacity, even given low volumetric flow of the coolant, a plurality of axial guide bars are arranged in the annular space, so that the coolant restrictedly flows in an axially wide-strip manner through the annular space within space segments arranged in a row in the circumferential direction, with an opposing flow direction in successive space segments.

The current invention relates to an apparatus for cooling and/or heating a motor vehicle, with at least one coolant pump for circulating a coolant in a cooling and heating system, with a main cooler segment, which has a main cooler inlet and a main cooler outlet, wherein the main cooler inlet is at least intermittently connected to at least one coolant outlet of an engine to be cooled, in particular an internal combustion engine, of the vehicle, and its main cooler outlet is connected to at least one coolant inlet of the engine, and with at least one other, secondary cooler segment provided in addition to the main cooler segment and at least one other unit to be cooled, which is connected to the cooling and heating system, and the apparatus have at least one bypass line with a bypass valve, which is associated with the at least one secondary cooler segment and is disposed parallel to this secondary cooler segment in the cooling and heating system of the motor vehicle.
摘要:
An internal combustion engine having an exhaust gas recirculation device for recirculating exhaust gas of the internal combustion engine to a fresh-air side of the internal combustion engine. For this purpose, it is provided that the exhaust gas recirculation device has at least one compressor for compressing the exhaust gas supplied to the fresh-air side of the internal combustion engine.
摘要:
A device for utilizing the waste heat of an internal combustion includes a single-stage or multi-stage supercharging device, which is designed as an exhaust-gas turbocharger in particular. The single-stage or multi-stage supercharging device is assigned an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, in particular a steam circuit.
摘要:
A method for operating an internal combustion engine (10) having a steam power plant (12), in which the exhaust gas of the internal combustion engine (10) at least indirectly heats the steam and this steam drives a turbine (26), the steam power plant (12) being sometimes, in particular at the beginning of operation, initially operated in a protection operating mode, in which the protection of the turbine (26) from damage by water droplets has priority.

A biased support for booms that can pivot about a pin, for pivoting travel tracks for vehicles that run on rails, such as trolley travel tracks on booms. The booms are mounted to pivot via pins, the lock on the boom and slide plates on the upper and lower bearing points of the lock. At least one of the two slide plates in the upper bearing point is mounted elastically, so that when the boom is pivoted into the operating position, the entire lock is biased vertically and the pin is relieved of stress.
