A dust cover is configured to cover an outer side of a damper extending in a predetermined direction. The dust cover includes bellows portions and a flange portion. The bellows portions are inclined alternately toward a radially outer side and a radially inner side in an axial direction. The flange portion extends radially outward from a cylindrical portion of the dust cover. The flange portion protrudes radially outward from the cylindrical portion of the dust cover by a dimension larger than a height dimension in a radial direction between a radially inner end and a radially outer end of each of the bellows portions. A thickness of the flange portion is larger than a thickness of the radially outer end of each of the bellows portions.

A method for mounting a sealing device between a housing of an air-conditioning installation and a partition wall present in the motor vehicle, includes the following measures (a) arranging the housing and the partition wall relative to one another so that a housing aperture present in the housing and a wall aperture present in the partition wall are positioned adjacently to one another, (b) arranging a sealing device having a frame-shaped sealing body formed as profile part, which in profile is formed substantially V-shaped with a first and second leg, between the two apertures, (c) reducing a distance between the two apertures by moving the housing towards the partition wall until a transition connecting the legs with one another folds over towards the wall aperture or away from the same.

A seal assembly in an apparatus including a housing, a housing bore defined by the housing, a shaft extending through the housing bore, and a shaft bore defined by the shaft. The housing bore includes an annular seal chamber between the housing and the shaft. The seal assembly includes a flexible tubular seal surrounding the shaft within the seal chamber. The tubular seal has a shaft end sealingly connected with the shaft and a housing end sealingly connected with the housing. The tubular seal divides the seal chamber into an interior seal chamber which is sealed from an exterior of the housing and an exterior seal chamber which is sealed from an interior space of the housing. At least one seal pressure balancing port is defined by the shaft and extends between the shaft bore and the exterior seal chamber.

The invention relates to an elongated rotary slip stub (50); a tube sleeve (60) coaxially moving to the slip stub (50); a bearing assembly (20) mounted on the slip stub (50) with a roller (24) close to a movable end (64) of the tube sleeve (60); and a driveshaft comprising a bellow (10) fixed at a distal end (12) to the adjacent tube sleeve (60) from an outer periphery (62). The driveshaft comprises a retaining part (40) provided on the suspension devide (20) and holding the bellow (10) in the suspension devide (20) such that the bellow (10) are fixed directly to the suspension devide (20) from a proximal end (16).

A Stirling cycle machine with a liquid fuel/gaseous fuel burner. The burner may include a preheater to capture the thermal energy of the exhaust. The burner directs the preheated air to each burner head, where it enters a prechamber. Each burner head includes a fuel nozzle that directs liquid or gaseous fuel into the prechamber. The prechamber is fluidically connected to a combustion chamber via a prechamber nozzle that has a smaller opening than the prechamber. The burner head ignites the fuel air mixture in the prechamber with an ignitor located above or within the prechamber. The flame is initially lit as a diffusion flame in the prechamber. The flame is pushed out of the prechamber into the combustion chamber by an increased air flow rate. The liquid fuel from the nozzle now evaporates in the prechamber and forms a prevaporized flame in the combustion chamber.
