Abstract: In order to provide a connecting device for connecting two components which enables two components to be connected, it is proposed that the connecting device include the following: a decoupling element; a sleeve for accommodating and guiding a connecting element, wherein the sleeve includes a base body which includes the following: a hollow cylindrical guidance section in which a connecting element is guidable; an axially limiting section which projects outwardly away from the guidance section in a radial direction; a radially outward limiting section which adjoins the axially limiting section and which together with the guidance section and the axially limiting section forms an annular seating section for accommodating the decoupling element.

Abstract: In order to improve an oil separator unit, in particular an oil separator unit provided for vehicle drives, comprising an oil separator housing with a drainage system and a check valve unit which is formed from a valve seat and a valve element which comprises a valve member of an umbrella-like design and consisting of an elastomer, in such a manner that it can be produced as inexpensively as possible, on the one hand, and, on the other hand, the wear on the valve element is, however, considerably reduced or occurs to as low a degree as possible, it is suggested that the valve member of the valve element be held on an insert part and that the insert part be insertable, for its part, into an insert part receptacle in a valve housing.

Abstract: In order to provide a drainage device, for example an oil drainage device used in particular for crankcase ventilation in motor vehicle engines, which reliably prevents an undesired liquid reflux and can be produced easily and inexpensively, it is proposed that the drainage device comprises a fluid line and a drainage valve arranged in the fluid line, wherein the drainage valve comprises a floating body that opens a fluid passage in an open position and closes it in a closed position.

Abstract: In order to provide a connecting device for connecting two components which enables two components to be connected in a reliable and noise-reducing manner, it is proposed that the connecting device include the following: a decoupling element; a sleeve for accommodating and guiding a connecting element, wherein the sleeve includes a base body which includes the following: a hollow cylindrical guidance section in which a connecting element is guidable; an axially limiting section which projects outwardly away from the guidance section in a radial direction; a radially outward limiting section which adjoins the axially limiting section and which together with the guidance section and the axially limiting section forms an annular seating section for accommodating the decoupling element.

Abstract: In order to produce a combination of a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion, a washer incorporating a passage opening the diameter of which is smaller than the external diameter of the threaded portion, and a sleeve the internal diameter of which is greater than the external diameter of the threaded portion, whereby said combination can be produced in a simple manner but nevertheless ensures that the sleeve and the washer are held securely on the screw member, it is proposed that the sleeve have at least one projection which engages in a recess provided in the washer, wherein the sleeve is pressed against the washer in such a manner that the sleeve and the washer are connected together and held captive on the screw member.

Abstract: In order to provide a sleeve comprising a sleeve base body and a flange that is produced separately from the sleeve base body and protrudes in the radial direction beyond the sleeve base body, which is producible in a simple manner but nevertheless ensures secure retention of the sleeve base body and the flange, it is proposed that the sleeve base body comprise at least one projection which engages in a recess provided in the flange, wherein the sleeve base body is pressed against the flange in such a manner that the sleeve base body and the flange are connected together in captive manner.

Abstract: The invention relates to a process for producing a plastic part (10), especially in the form of a control valve housing part for a transmission in motor vehicles, with a plurality of fluid-carrying channels (12) which are bordered at least partially by side walls (14), of which some arranged next to one another border on an installation space (20) for holding at least one installation part which is prepared by means of one mold part (26) as part of the molding tool (18), a tool suitable for this purpose and a mold part produced according to this process.

Abstract: A screw-sleeve element has a screw having a screw shaft and a threaded region formed so that the screw shaft has a smaller diameter than an outer diameter of the threaded region; and a sleeve provided at an inner side with a narrow location having a diameter which is smaller than the outer diameter of the threaded region of the screw, so that the sleeve is non releasably arranged on the screw.
