摘要： An external gear type hydraulic pump or motor wherein the trunnions of gears in the chamber of the housing are surrounded by annular bearing members. The peripheral surface of each bearing member defines with the adjacent internal surface of the housing an arcuate gap whose width increases in a direction toward the respective end face of the corresponding gear. To this end, portions of or the entire peripheral surfaces of bearing members and/or portions of or the entire internal surfaces of the housing have a conical or spherical shape. The gaps are located in the low-pressure zone and reduce the likelihood of wear upon those end faces of bearing members which are adjacent to the end faces of the gears because the bearing members can tilt in response to increasing load without localized rubbing against the gears. Additional gaps can be provided between the end faces of the gears and the adjacent end faces of the bearing members to further reduce the likelihood of uneven wear upon the bearing members.

摘要翻译： 外部齿轮型液压泵或马达，其中壳体的腔室中的齿轮的耳轴由环形轴承构件包围。 每个轴承构件的外周表面与壳体的相邻内表面一起限定弓形间隙，其宽度在朝向相应齿轮的相应端面的方向上增加。 为此，轴承构件的外周表面的一部分或整个表面和/或壳体的整个内表面的整个或全部具有圆锥形或球形。 间隙位于低压区域，并减少了与齿轮端面相邻的轴承构件的这些端面上的磨损的可能性，因为轴承构件可以响应于增加的载荷而倾斜，而不会对齿轮进行局部摩擦 。 可以在齿轮的端面和轴承构件的相邻端面之间提供额外的间隙，以进一步降低在轴承构件上不均匀磨损的可能性。

摘要： An external gear pump wherein the gears are installed in an eight-shaped compartment of a central housing section which is flanked by two covers. The outlet port of the housing communicates with two arcuate recesses for metallic inserts which are biased against the adjacent gears by fluid pressure in the outlet port whereby the inserts urge the gears against those portions of the internal surface of the central housing section which are located opposite the recesses. Such portions of the internal surface are formed with narrow first cutouts which communicate with the outlet port. The internal surface is further formed with relatively wide additional cutouts which are located between the first cutouts and the recesses and communicate with the inlet port. The force which is produced by fluid in the cutouts opposes the force which urges the gears against the internal surface of the central housing section to thus reduce the force with which the stubs of the gear shafts are urged against the housing.

摘要： A gear-type fluid displacing machine includes a housing having a chamber and two side sections overlying opposite ends of the chamber, a pair of mating gears in the chamber for generating a high pressure area therein as the gears rotate, and annular bearing members surrounding trunnions associated with the gears at opposite ends of the chamber each of the bearing members having an end which faces one of the side sections of the housing and being formed with a groove. The sealing arrangement includes a generally U-shaped resilient sealing element in each of the grooves and having an open side in communication with the high pressure area. The sealing element has at least one wedge-shaped leg which is pressed into sealing contact with an associated side section by its own resilience and by the force exerted by the pressure fluid entering the open side of the element from the high pressure area.

摘要： The invention relates to a method, and the equipment necessary for implementation thereof, for the unnoticeable detection of armed persons in the region giving access to objects that require protection and for the detention of such persons by surprise. Detention by surprise prevents individuals prepared to do violence from being able to run amok or take hostages in order to secure their own release.
