Abstract: A screw compressor for a utility vehicle has a rotor housing, in which screw rotors of the screw compressor are arranged, a housing cover, and an air outlet pipe arranged on an output side of the housing cover and having a riser. The air outlet pipe has at least one oil separator.

Abstract: An arrangement of screws for a screw compressor for a utility vehicle includes at least one female screw and at least one male screw. The female screw and the male screw each have teeth that engage with one another. The teeth of the female screw have a roll-off tooth flank which is provided for rolling-off a tooth flank of the male screw. The roll-off tooth flank has a convexly rounded roll-off tip region in the tip region, which has a first radius, wherein a tooth base is provided between two neighboring teeth of the female screw, which is connected to the roll-off tip region via a flat transition region. The tooth base between two teeth of the female screw is substantially concavely rounded and has a second radius, wherein the second radius is approx. 2.5 to 3.5 times greater than the first radius.

Abstract: An arrangement for a screw compressor of a utility vehicle has at least one housing part of the screw compressor and a baffle. The housing component has at least three baffle receptacle recesses, wherein at least one baffle receptacle recess is arranged outside an imaginary line connecting the two other baffle receptacle recesses. The baffle has at least three fingers which, in the assembled state of the arrangement, are each inserted in a baffle receptacle recess associated with the respective finger.

Abstract: A minimum pressure valve for a screw compressor for a vehicle, in particular a utility vehicle, is provided with a housing; a valve insert opening which is formed in the housing; a valve insert which is inserted into the valve insert opening and has a valve piston bore; a valve piston, a valve piston section of which is guided in the valve insert in a movable manner in the valve piston bore; at least one fluid inlet channel; and at least one fluid outlet channel. The fluid inlet channel has at least one valve seat on the inlet channel end which faces the valve piston, wherein the valve piston can be set against the valve seat in order to close the minimum pressure valve such that the fluid inlet channel and the fluid outlet channel are separated in a closed position of the valve piston. The valve seat has a valve seat diameter dA, and the valve piston section has a valve piston section diameter dB. The ratio of the valve piston section diameter dB to the valve seat diameter dA ranges between ca. 0.6 and ca.

Abstract: A screw compressor system for a utility vehicle has at least one screw compressor, at least one screw compressor drive with an output shaft, at least one driven screw with a screw drive shaft section. The output shaft and the screw drive shaft section are essentially coaxial.

Abstract: A screw compressor for a utility vehicle has a housing, wherein, in the operationally ready and assembled state of the screw compressor, an oil sump is provided in the housing. A magnet is arranged in the oil sump.

Abstract: A system for a utility vehicle has a screw compressor and an electric motor. The electric motor drives the screw compressor. The electric motor is connected to the screw compressor by a flange which has at least one cooling connection, and a cooling channel is provided in the flange.

Abstract: A screw compressor for a utility vehicle includes a housing. The housing is filled with oil. At least one pair of compressor screws are mounted in the housing and serve to compress air supplied to the screw compressor. In the assembled state, a heat exchanger is directly placed onto and installed on the housing, by which heat exchanger the temperature of the oil contained in the housing can be controlled.

Abstract: Compressor for generating compressed air for a commercial vehicle, having a housing with a piston chamber in a crankcase and a dead space which is configured at least in the cylinder head. The compressor has a valve device with a valve element which has an actuating section and a shut-off body for separating the dead space from the piston chamber, wherein the shut-off body can be lifted up from a valve seat in the direction of the piston chamber in order to open the valve device. The valve element is configured in one piece with the actuating section.

Abstract: A piston compressor for compressing a gas, which optionally can be disconnected from a drive device by a clutch, has an inlet valve, which is arranged between an inlet line for gas to be compressed and a compression chamber of the piston compressor, and an outlet valve, which is arranged between the compression chamber of the piston compressor and an outlet line for compressed gas. The piston compressor includes a closing device which closes the outlet line with respect to the compression chamber.

Abstract: A piston compressor is provided for compressing a gas, which optionally can be disconnected from a drive device by way of a clutch. The piston compressor has an inlet valve, which is arranged between an inlet line for gas to be compressed and a compression chamber of the piston compressor, and an outlet valve, which is arranged between the compression chamber of the piston compressor and an outlet line for compressed gas. The piston compressor has a venting device, by which compressed gas can be led out of the compression chamber.

Abstract: A crankcase assembly for a reciprocating machine is provided in which a crankcase having at least one cylinder with a wet cylinder liner arranged therein. A cylinder head for charging and discharging pressurized gas is mounted on the crankcase and a cylinder head gasket for preventing leakage of pressurized gas out of the cylinder is arranged between the crankcase and the cylinder head and is running circumferentially spaced from the inner wall of the cylinder liner. A circumferential coolant channel is formed between the inner crankcase wall and an outer wall of the cylinder liner, wherein a lower sealing means is arranged between the inner crankcase wall and the cylinder liner on the crankshaft side of the coolant channel for preventing leakage of coolant fluid. An upper sealing means is arranged between the inner crankcase wall and the cylinder liner on the cylinder head side of the coolant channel for preventing leakage of coolant fluid.
