Abstract: An oil filter assembly (10) has a receiving chamber (18) that can be closed by a cover element (14) and a spring-loaded supporting tube (22) that is fixed in the receiving chamber and is designed to receive a filter element (20) that can be radially traversed by oil. The supporting tube (22) is axially displaceable between an operating position and a drain position in such a way that, in the operating position when the receiving chamber is closed by the cover element (14), the tube closes a drain opening (42). When the receiving chamber is open in the drain position, the tube releases the drain opening. The supporting tube is mounted to rotate through a rotational angle that is limited by two rotational stops (41, 43) in the housing and the cover element has follower sections (66, 68, 70) that co-operate with the supporting tube and/or filter element to rotate the supporting tube through the rotational angle when the cover element is screwed on and/or unscrewed.

Abstract: An oil filter arrangement, has a housing (12) with a receiving space (18) for a filter element (20) which can be inserted into the housing and through which oil can flow radially, with an oil inlet (34) and an oil outlet (32), and with a supporting tube (22) which is present in the receiving space and supports the filter element. The supporting tube is inserted into the receiving space and is fastened to the housing in such a manner that it remains in the housing when the filter element is exchanged.

Abstract: An oil filter arrangement comprises a housing, which has a receiving chamber for a filter element which can be cross-flowed in a radial manner by oil and which can be inserted into the housing, a support tube which supports the filter element when it is inserted, a housing cover which closes the receiving chamber, and a drainage channel which is provided in the base area of the receiving chamber. The support tube is fixed to the housing and it remains therein when the filter element is replaced and that a drainage plate, which comprises closing means for closing the drainage channel and which is arranged in an axially displaceable manner, to a limited extent, on the support tube, is arranged in the base area of the receiving chamber.

Abstract: An oil filter assembly (10) comprises a housing (12) that has a holding space for a filter element (20), which can be placed inside the housing and through which oil can radially flow, an oil inlet, an oil outlet, and a supporting tube (22), which supports the filter element. A guide (62) for a compensating body of the outlet valve is provided on a part that is separate from the housing (12). The compensating body (58) serves to compensate for axial tolerances of the housing and/or of the filter element.

Abstract: An oil filter arrangement (10) comprises a housing (12) provided with a reception compartment for receiving a filter element (20), which is insertable in the housing and which the oil radially passes through, an oil output and a support tube (22) which is arranged in the reception compartment and supports the filter element (20), wherein a bypass valve (24) which is arranged in the support tube (22) opens when a limiting pressure is exceeded and which the oil flowing from the oil input to the oil output passes through by passing the filter element, said bypass valve comprising a valve seat (36), a valve body (38) interacting therewith and a cage-like lid part (49). The support tube (22) and the lid part (40) are embodied in a single piece form of a plastic material.

Abstract: An oil filter assembly with a housing which comprises a receiving chamber for a filter element can be inserted into the housing and through which oil can flow in a radial direction, and with a housing lid that closes the receiving chamber, wherein a pure oil or unfiltered oil opening that is surrounded by a pipe socket, and a channel chamber extending in the longitudinal direction of the receiving chamber are provided at the bottom of the receiving chamber. A drainage plate is provided in the bottom area of the receiving chamber, which is disposed on the pipe socket such that it can be axially displaced to at least a certain degree and has a closing means, wherein at least one pressure spring is disposed between the drainage plate and the bottom such that in the operating position when the housing is closed and the filter element is inserted, the drainage plate is loaded by the filter element against the spring force and the closing means closes a drainage opening of the channel chamber.

Abstract: The invention involves a countercurrent heat exchanger for condensation laundry dryers of the type that is the object of DE 198 38 525 A1. In order to increase the cooling output of the heat exchanger plates (12) stacked into a heat exchanger plate stack (10), which each contain at least one humid air channel (14) and are made out of thermoplastic plastic or from a film consisting of a heat-conducting metal, the heat exchanger plates (12) are equipped with several struts (32) that form cooling lamellas which project outward from them and extend perpendicularly to the humid air channel (14), and which form pockets that open into the humid air channel (14).

Abstract: A coolant and/or lubricant transport device supplies lubricant or circulating cooling water in internal combustion engines. The pump can be driven by an electric motor which can be controlled in dependence upon a control quantity of a continuous controller. The pump can be temporarily stopped or operated to work with an appropriately reduced output to achieve a desired control value.

Abstract: The invention concerns a use of a heat exchanger for temperature control or air conditioning in rooms. The heat exchanger has a media guiding body having two groups of crossing channels (24,46) or (110,112) for media to be separately guided, wherein one channel group (24;110) is formed like a pipe and the other channel group (46;112) is formed like a shaft, wherein the latter channel group (46;112) is formed by bridges (30;126) provided on the outside at a distance from one another and oriented transverse to the pipe axis, wherein the pipe-like channels (24;110) and the bridges (30;126) are commonly produced from at least one formed sheet (140) consisting of thermoplastic material (32) or of a thermally conducting metal.

Abstract: A plastic toothed wheel for a toothed wheel pump comprises a wheel body (20) having external or internal teeth. To keep the weight of this toothed wheel as low as possible, its teeth (26) have at least one cavity (32) accessible from at least one end face of the tooth. Toothed wheel pumps having such toothed wheels for supplying and pressurizing engine oil in automotive vehicle engines avoid splashing losses caused by the cavities (32) by closing the cavities or filling them up with a temperature and media resistant foam material (66).
