  • Publication number: 20180372087
    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.

  • Publication number: 20180291883
    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.

  • Publication number: 20180266407
    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.

  • Publication number: 20170218934
    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.

  • Patent number: 8807314
    Abstract: A clutch actuator controlled by a pressure medium, in particular for a compressor clutch of a commercial vehicle has an actuating piston displaceably disposed in a housing in an axial direction. An end of the actuating piston is supported in the axial direction on an elastic membrane, sealing a first region of the housing off from a second region of the housing. The elastic membrane includes a raised area on the side opposite the actuating piston. The clutch actuator can be used in a compressor clutch for a commercial vehicle.

  • Patent number: 8512007
    Abstract: A compressor system and method of operating same are provided for the compressed air supply of a commercial vehicle, wherein the compressor system includes a compressor for compressed air generation, a transmission for transmitting torque from a drive motor to the compressor, a clutch for disconnecting the connection between compressor and drive motor, and a control unit for opening and closing the clutch. The control unit is capable of opening the clutch in the event a settable maximum allowed compressor speed or motor speed of the drive motor is exceeded and to close the open clutch temporarily when the motor speed is greater than the maximum allowed motor speed.

  • Patent number: 8496450
    Abstract: A compressor system supplies compressed air to a commercial vehicle. The compressor system includes a compressor, a clutch, and a hydraulic pump and can be driven by way of a drivetrain. The compressor can be completely disconnected from a driving engine by way of the clutch. The drivetrain encompasses a geared drive mechanism which allows the hydraulic pump to be driven, and the clutch is arranged between the geared drive mechanism and the compressor. A method for operating the compressor system is provided.

  • Patent number: 8147215
    Abstract: A reciprocating-piston compressor having at least two working cylinders arranged in series, along a cylinder axis is described. The compressor includes a piston in each of the cylinders, guided in an axially movable manner, and a common axially actuated piston rod of the pistons, extending through a passage opening in a partition between the at least two working cylinders. The at least two working cylinders are sealed off with respect to one another in a region of the common axially actuated piston rod, exclusively by a non-contact seal. The axial seal has an axial gap seal formed between a radially outer circumferential surface of the common axially actuated piston rod and a radially inner circumferential surface of the passage opening.
