    摘要： The invention relates to an external gear machine (1) in particular an external gear pump or an external gear motor, having at least two gears (3, 4) that mesh with each other in external engagement, wherein the gears (3, 4) are surrounded by a housing (10), wherein one gear (4) has at least one bearing journal (7, 8) and the other gear (3) has a driving or driven journal (5), which are in each case mounted in a bearing bushing (38) so as to respectively be rotatable about a rotation axis (13, 14), wherein a bearing sleeve pp with an anti-twist element is arranged in the bearing bushing (38). In order to improve the external gear machine, in particular with regard to the materials that can be used for producing the bearing bushings and/or the service life, the anti-twist element of the bearing sleeve is arranged in a through-hole of the bearing bushing and is combined with a filter device and/or throttle device via which a working medium of the external gear machine (1) reaches the bearing sleeve.

    摘要： An air compressor includes a compression mechanism for compressing intake air and discharging the compressed air, and an intake chamber portion through which intake air is introduced into the compression mechanism. The intake chamber portion has an inlet of intake air and an outlet connected to the compression mechanism. The intake chamber portion is integrated with the compression mechanism. The intake chamber portion has therein a partition wall extending in the direction from the inlet toward the outlet to form plural flow passages in the intake chamber portion. The plural flow passages have different flow path lengths and connect between the inlet and the outlet.

    摘要： A lubricant pump includes a housing in which at least one pair of intermeshing gear wheels is arranged for conveying lubricant. One gear wheel is rotatably supported on a drive shaft and the other gear wheel is rotatably supported on an axially shiftable displacement unit for adjusting a variable flow volume. Axially displaceable in a housing receptacle is a control piston for hydraulically adjusting the position of the displacement unit. The control piston is configured as composite structural part and has a central longitudinal shaft and cylinder rings which include control edges for clearing or closing control channels feeding into the receptacle. The cylinder rings are made from a material which reduces friction and/or wear with respect to the receptacle, and the central longitudinal shaft has at least one section made from a material having a coefficient of thermal expansion at least substantially corresponding to the one of the receptacle.
