摘要:
Axial piston compressor, especially a compressor for the air-conditioning system of a motor vehicle, having a housing and, for drawing in and compressing a coolant, a compressor unit arranged in the housing and driven by means of a drive shaft (104), the compressor unit comprising pistons moving axially back and forth in a cylinder block and comprising a swash plate (107) which drives the pistons and rotates together with the drive shaft. For a predetermined mass of the swash plate (107) moved in rotation on the one hand and/or a particular mass moved in translation on the other hand, the mean radius governed by the geometry and/or by the density distribution and/or the mean height of the swash plate (107) or of the pivotal portion thereof is/are so selected that the centrifugal forces occurring on rotation of the swash plate (107) are sufficient to counteract the pivotal movement of the swash plate (107) to provide deliberate regulation and thereby to influence, especially to reduce or to limit, the piston stroke and, consequently, the quantity delivered.

摘要:
In an axial piston compressor for a refrigerant, in particular for a vehicle air conditioner, with a housing (12) in the interior of which is disposed at least one bearing (22, 24, 26, 48, 56, 58, 60, 64), with an output conduit (34) for the compressed refrigerant, and with a lubricant that is present in the interior of the housing (12), the lubrication is to be improved. For this purpose there is provided in the housing at least one lubricant channel to conduct lubricant to the bearing, as well as a lubricant separator (36) that is connected to the output conduit (34) for the refrigerant and incorporates a collection chamber (40) that contains the lubricant separated from the compressed refrigerant and is connected to the lubricant channel (46) by a feed line (42), such that the lubricant is propelled out of the lubricant separator and into the lubricant channel entirely on the basis of the pressure difference between the compression pressure of the lubricant and the interior pressure of the housing.

There is proposed a test wheel arrangement (1) for testing a motor vehicle while the tyres are stationary, which test wheel arrangement (1) has a shaft section (5) which can be attached to a wheel hub (7) of a motor vehicle and on which a test wheel (3) is mounted to be freely rotatable.
摘要:
An air conditioner for motor vehicles has a refrigerant circuit in which the refrigerant is brought into a wet vapor state. The refrigerant circuit is comprised among other things of at least one compressor (37) and a pressure ramming machine (14′) which serves as an expansion device. By means of the pressure ramming machine (14′), energy is recovered during the expansion process which can be used in the circuit for compressing the refrigerant. In addition, a method for operating an air conditioner for motor vehicles is described, according to which a pressure ramming machine is integrated into the refrigerant circuit and refrigerant is brought into a wet vapor state in the pressure ramming machine (14′).
摘要:
Vehicle air-conditioning system, in particular CO2 air conditioner, the refrigerant cycle of which comprises the following components: a compressor, a refrigerant cooler, an internal heat exchanger between the refrigerant-cooler side and the evaporator side, an expansion valve, and an evaporator. To switch the air-conditioning system from cooling-mode operation to heating-mode operation, between the compressor and the refrigerant cooler there is integrated an auxiliary heat exchanger corresponding to a cooling circulation on the engine side, such that downstream of the auxiliary heat exchanger there is disposed an expansion valve by means of which during heating-mode operation the refrigerant can be throttled to a lower pressure.

An adjustable radial pump for feeding a cooling medium for a motor vehicle having a housing, a pump wheel provided with pump vanes, the pump wheel being supported in the housing and driven by a motor, the housing having at least one integrated inlet and outlet opening, an adjusting device for providing an adjustment of the medium to be fed independently from the rotary speed of the motor, the adjusting device being operatively connected with a sleeve which is adjustable by the adjusting device over the pump vanes in an axial direction.
摘要:
There is disclosed an novel refrigeration apparatus and a method of refrigeration. The novel refrigeration apparatus comprises a desorber/evaporator, a gas/liquid compressor operatively connected to said desorber/evaporator, a resorber/condenser operatively connected to said gas/liquid compressor, an expansion device operatively connected to said resorber/condenser and to said desorber/evaporator and a circulating refrigerant comprising carbon dioxide and a liquid co-fluid in which the carbon dioxide is differentially soluble. The refrigeration method comprises compressing carbon dioxide gas and a liquid co-fluid in a gas/liquid compressor to an increased pressure, such that carbon dioxide at least partially dissolves in the liquid co-fluid, and reducing the pressure on the liquid co-fluid containing the dissolved carbon dioxide so that dissolved carbon dioxide comes out of solution with the liquid co-fluid, and recirculating the gaseous carbon dioxide and liquid co-fluid to the gas/liquid compressor.

A drive arrangement for at least one auxiliary system of a motor vehicle, having an internal combustion engine, at least one supplementary motor, and a gear, is provided. The gear is a planetary gear which is operatively connected to the engine and the at least one supplementary motor each via a respective input shaft, and to the auxiliary system via an output shaft.
摘要:
A method and a device for the control/regulation of the heat flows caused by heat generators and heat consumers in a motor vehicle, at least on the basis of a momentary load state of the motor vehicle engine and the momentary vehicle operating conditions and ambient conditions. A control/regulation device makes a forecast of the load state of the engine cooling system lying ahead, on the basis of a model that takes into consideration driving condition-relevant quantities and the thermal inertia of the engine cooling system and of engine load-relevant ambient conditions lying ahead, recorded by a satellite navigation system, and carries out a corresponding control/regulation of all heat flows in the motor vehicle, especially of the engine cooling system.
