A heat exchanger assembly may include an intercooler and a housing which encloses said intercooler. The housing may be part of a charge air line. The housing may include a charge air inlet, a charge air outlet and an opening through which the intercooler can be inserted into the housing from one side. The housing may also include a recess on the side opposite the opening, into which recess the intercooler engages. The heat exchanger assembly may include an elastic seal arranged in the region of the recess between the intercooler and the housing. The seal may be configured to at least one of bridge the deformation of the housing occurring during pressure pulsations, bridge relative movements between the intercooler and the housing, and tightly connect the intercooler to the housing in all operating states preventing an undesirable bypass flow.

Heat exchanger assembly

A fresh air supply device for an internal combustion engine may include a filter element arranged in a filter compartment. A charge-air cooler may be arranged in a cooler compartment. A one-piece housing may integrally include the filter compartment and the cooler compartment. The charge-air cooler may have a coolant inlet, a coolant outlet and an internal coolant path which connects the coolant inlet to the coolant outlet. The internal coolant path may be coupled in a heat-transferring manner to a charge-air path extending inside the housing and through the cooler compartment.

Fresh air supply device

A filter appliance may include a filter housing and a ring filter element having an axis and being mountable in the filter housing. The filter element may include a first axial end disc having a protruding pin configured to engage into a channel of the filter housing. The filter housing may have an interior including a first region and the ring filter element may include a second region associated with the first region. A guide contour may be arranged on one of the first region and the second region, and a first guide element and a second guide element may be disposed on the other of the first region and the second region. The guide contour may include a first axial groove and a second axial groove configured to receive the first guide element and the second guide element to define a key and lock interaction.

Filter appliance

A filter device having a filter element received in a filter housing, the filter housing has an inlet and an outlet. The filter element separates a crude chamber that communicates with the inlet from a pure chamber that communicates with the outlet. The filter element has an axially and eccentrically projecting plug, which in an inserted state, is plugged into a plug receptacle formed within the filter housing, and wherein at least one signal generator recognizes at least one of a presence and an absence of the plug in the plug receptacle, generating at least one signal.

Filter device

A hollow plastic part may include at least two plastic shells connected with one another at a respective edge along at least one joining plane. Each plastic shell may have at least a first component and a second component, wherein the plastic of the first component may have a lower melting temperature than the plastic of the second component. The first component may extend on at least one plastic shell in a caterpillar-like manner along at least part of the respective edge of the second component of this plastic shell.

Hollow plastic piece

An oil purifying liquid filter, having an annular ring element receiving space, wherein the ring element has two axial end disks, a cover selectively fastened to a housing to close the receiving space, an inlet that is formed within the housing on a crude side, an outlet that is formed within the housing on a pure side, a first additional opening that is formed within the housing, a second additional opening that is formed within the cover, a first closure that is formed on the first end disk of the filter element in order to close the first additional opening, and a second closure that is formed on the second end disk of the filter element to selectively close the second additional opening.

Method for purifying oil and apparatus therefor

The invention relates to a valve unit for at least one of influencing and controlling a gas flow in an internal combustion engine comprising at least one valve member for modifying a cross-section of a gas flow-carrying channel through which a fluid flows and a drive train for rotatingly driving the at least one valve member. The drive train comprises an input shaft, which is drivingly coupled to a drive device in the mounted state, and at least one valve member shaft which is non-rotationally connected to the valve member. It is especially advantageous if the drive train comprises at least one phase adjuster for drivingly coupling the input shaft and the valve member shaft, a rotational position of the shafts in relation to each other being adjustable by the phase adjuster.

Valve unit for an internal combustion engine and internal combustion engine

A bearing device for supporting a camshaft in a cylinder head is disclosed. The bearing device comprising at least one locking contour, which is connected with at least one counter-locking contour configured at a cylinder head cover, such that the cylinder head cover is clamped tightly against the cylinder head by the bearing device.

Internal combustion engine with a camshaft bearing device

The invention relates to a liquid filter, especially an oil filter, for cleaning lubricating oil, especially for internal combustion engines of automobiles, comprising an upright filter housing which contains a receiving area for a ring-shaped filter insert that is inserted into said receiving area, an inlet channel for unclean liquid, an outlet for clean liquid, and an additional discharge channel which is exposed when the ring-shaped filter insert is removed. An eccentrically projecting pin is moulded to a lower end plate and sealingly penetrates an opening of the discharge channel when the ring-shaped filter insert is introduced into the filter housing. According to the invention, a ramp is configured on the floor of the receiving area and is positioned in such a way that when the ring-shaped filter insert is introduced into the filter housing, the pin lies on said ramp and when the ring-shaped filter insert is rotated about its longitudinal axis, the pin slides downwards along the ramp and enters the opening of the discharge channel at the lower end of the ramp. This improves handling.
