    • In an axial piston compressor, especially a swash plate compressor for generating compressed air in motor vehicles, an oil-lubricated drive and an air compressor part that operates without oil are provided. The pistons that travel in cylinder bores under the guidance of a swash plate each have at their backs the intake chamber formed by chambers and a pressure chamber on the front. Intake valves are mounted on the pistons, while pressure valves are provided in cylinder head, cooled by cooling oil or water. The seal between oil-lubricated drive and the compressor part that operates without oil is provided by sealing elements that act on the outer circumference of the piston rods of the pistons. When cooling oil is used to cool the cylinder head, this oil simultaneously serves as the lubricating oil for drive

    • There is provided a sealing device (10) for a unitised grease-or oil-lubricated package bearing assembly comprising a twin outer race (14) and two inner races (15, 16) arranged next to each other on a shaft (12), with their faces abutting. Typically, oil may be present between the said shaft (12) and the bore surfaces of the bearing inner races (15, 16), for the purpose of lubricating parts of the system adjacent to the bearing, but not the sealed, lubricated bearing itself. The scaling device comprises a substantially annular sealing portion (26) and the provision of a step (29) in the abutting face of one of the inner races such that a substantially rectangular-section groove (30) is created on the outside diameter of the abutting inner races (15, 16). Located in the groove (30) is the annular sealing portion (26) of the annular sealing device (10) which is compressed between the side walls of the groove (30) to provide a barrier to (a) ingress of any oil or water present between the shaft (12) and the bores of the inner race assemblies (15, 16), (b) loss of oil which is part of the lubricant sealed within the bearing.

    • A safety belt retractor mechanism for vehicle passengers is described which has an apparatus for selectively relieving belt retractive tension on the passenger. The apparatus may be either manually or automatically engaged at a first extensive position of the belt corresponding to the buckled up position such that, for a single extractive movement of the belt by a first predetermined amount of "slack", the belt is locked against further retractive movement below that position, thereby relieving the retractive tension of the belt on the wearer. Further extensive and retractive movements of the belt beyond the tensionless position and less than a second predetermined amount, such as would result from passenger forward movements to reach controls, etc., result in normal retractive tension in the belt against the passenger until the passenger returns to the buckled up position. The apparatus then "remembers" this position and restores the slack to the wearer. Upon extractive movements of the belt greater than the second predetermined amount, or upon manual or automatic disengagement of the tensionless mode, the retractive tension of the belt below the slack position is restored until again reset by the passenger.The apparatus is distinctive in its use of a Geneva mechanism to drive a memory disk having a pair of cams on its surface at a reduced rate through a frictional clutch to operate a locking pawl cooperating with a ratchet disk attached to the spool of the belt retractor to lock and unlock the spool at the appropriate positions. A control arm indexes the memory disk relative to the locking positions and the Geneva mechanism permits significantly increased extensive movements of the passenger beyond the slack position without unlocking the mechanism, as well as increased accuracy of control over the belt slack and unlocking positions.
    • 描述了一种用于车辆乘客的安全带卷收器机构,其具有用于选择性地减轻乘客的带收缩张力的装置。 该装置可以手动地或自动地接合在对应于弯曲的上升位置的带的第一广泛位置处,使得对于皮带的单次提取运动通过第一预定量的“松弛”,带被锁定以进一步 在该位置下方的回缩运动,从而减轻了皮带在穿着者身上的回缩张力。 皮带超出无张力位置并且小于第二预定量(例如由于乘客向前移动以达到控制等)而导致的进一步的广泛和回缩的运动导致皮带抵靠乘客的正常回缩张力,直到乘客返回 到了弯腰的位置。 然后,该装置“记住”该位置并将松弛恢复到佩戴者。 当皮带的抽出运动大于第二预定量时,或者在手动或自动脱开无张力模式时,恢复到松弛位置以下的带的回缩张力,直到由乘客再次复位。 该装置在使用日内瓦机构时通过摩擦离合器以降低的速率驱动其表面上的一对凸轮的存储盘,以操作与附接到带卷收器的卷轴的棘轮盘配合的锁定爪,其特征在于 在适当的位置锁定和解锁阀芯。 控制臂相对于锁定位置指示存储盘,并且日内瓦机构允许乘客显着增加乘客超出松弛位置的大量运动,而不解锁机构,以及提高对皮带松弛和解锁位置的控制精度。

    • In a compressor that can be used for supplying compressed air in motor vehicles and also for stationary systems, permanent oil filling is provided for cooling a compressor pressure area including a cylinder head and for lubricating a transmission area including a drive shaft and swash plate. The pressure area of the compressor that can be heated by the heat of compression and friction and the transmission area of the compressor are separated from one another by check valves with a delivery pump wheel being provided which transports the oil between the transmission area and the pressure area in such fashion that the oil that is heated in the pressure area is cooled in the transmission area. By cooling the oil in the transmission area, it is possible for a middle housing section of the compressor housing, as well as a housing section delimited by a cylinder head and receiving the piston arrangement, to be made of plastic.
