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: A screw compressor system for a utility vehicle includes at least one screw compressor and at least one control and/or regulation unit for controlling and regulating the screw compressor.

Abstract: A compressor has a crankcase in which a crankshaft is rotatably mounted in a crankspace. The crankcase contains at least one cylinder space in which a piston, mounted eccentrically on the crankshaft by way of a connecting rod, can be driven in reciprocating motion. The crankshaft is connected, via a gearing having a modulus m, to a drive source, wherein the gear wheel arranged on the crankshaft engages with the gear wheel on the drive source. The axis of rotation of the crankshaft is offset with respect to the center axis of the cylinder space by an amount dl which is a whole multiple of m/2. The center axis of the cylinder space is understood as the axis which proceeds from the center point of the base area of the cylinder space, perpendicular to this base area, and along which the piston moves.

Abstract: An arrangement has a housing, which has a receptacle or an opening, and a cylindrical insert, which is mounted in the receptacle or opening via at least one interference fit. The insert has a peripheral groove, and therefore the insert is both fastened against the housing and sealed against the housing in a liquid- and/or gas-tight manner by way of material of the insert and/or housing that has been pressed into the groove during the assembly. The material of the insert and/or of the housing is displaced in the case of an interference fit. The groove provides a defined location to which the material can preferably flow. After the assembly has been concluded, the insert is locked against the housing by the material located in the groove. At the same time, the material acts as a seal between the insert and the housing. A separate seal in the region of the press fit becomes dispensable.

Abstract: A screw compressor system for a utility vehicle includes at least one screw compressor and at least one control and/or regulation unit for controlling and regulating the screw compressor. The control and/or regulation unit is designed such that the screw compressor is prevented, for a determined period of time, from re-starting after being stopped.

Abstract: A screw compressor for a utility vehicle has at least one female screw, at least one male screw that meshes with the female screw, and at least one screw compressor drive which drives the female screw.

Abstract: A screw compressor for a utility vehicle has at least one housing and a relief valve. The relief valve includes a spring-loaded closure mechanism with at least one spring and at least one closure element. The spring has a spring force which is dimensioned such that it actuates the closure element when a predefined minimum pressure above the atmospheric pressure is reached.

Abstract: A screw compressor for a utility vehicle includes at least one housing, at least one housing cover and at least one rotor housing. At least one seal is provided, wherein, when assembled, there is an oil sump in the housing, and the seal is arranged between the housing cover and the rotor housing and projects out of the oil sump with respect to the assembled state. The seal is formed as a sealing plate and has multiple passage openings.

Abstract: A screw compressor system for a utility vehicle has at least one screw compressor, at least one screw compressor drive, at least one temperature probe and at least one control and regulation unit. The control and/or regulation unit is connected to the screw compressor drive and to the temperature probe and is designed and configured such that it controls, in accordance with a temperature threshold signal obtained from the temperature probe, the screw compressor drive with respect to a rotational speed.

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.

Abstract: A screw compressor system for a utility vehicle has at least one screw compressor, at least one screw compressor drive and at least one control and/or regulation unit. The control and/or regulation unit is connected to the screw compressor drive and is designed and configured such that it monitors, when the screw compressor is in operation, the ratio of idle time and switched on time of the screw compressor drive and this ratio controls and regulates to a predetermined range.

Abstract: A method produces a housing of a rotary screw compressor, the housing having at least one housing body and at least one housing cover.
