摘要： A hydraulic flow control apparatus is provided which is adapted to provide a constant pressure differential between a pump and an external load. the apparatus includes a housing, and a balance piston slideably mounted therein. The pump pressure acts to bias the piston in a direction toward a pump bypass position, and the piston is urged in the other direction and toward its operating position by the consumer pressure and a spring. Means are also provided whereby the pressure of the pump necessary to move the piston toward its bypass position and against the force of the spring, may be minimized during operation in the idling mode, to thereby minimize power consumption.

摘要： A device for black and white, color, stereo picture, holographic picture and stereo and other amplified sound reproduction and reception is described, which is characterized by a hinged housing A and B, one portion of which contains the picture reproduction screen 1. A pair of directional speaker units 2a+2b are integrated in the hinge section of the device. Sound and picture reception units are located in the housing along with touch controls and auxiliary sockets which extend through the wall of the housing B and are located at the surfaces 3, 4a, and 4b.

摘要： The present invention relates to a high-pressure hydraulic valve in which the housing (1) at least and also preferably the operational parts, such as the main control piston (3), the manometer piston (6) and the like which are arranged inside said housing (1) and influence the hydraulic oil flow, are made of an aluminium alloy that can be hardened and tempered. The weight of the high-pressure hydraulic valve can therefore be substantially reduced. The surfaces of the parts made of the aluminium alloy that can be hardened and tempered are advantageously submitted to anodic oxidation in order to increase even more their wear resistance. This type of high-pressure hydraulic valve with a particularly light weight is mainly intended for use in mobile hydraulic systems such as those used in mobile cranes, in lifting platforms and in excavators.
摘要翻译：本发明涉及一种高压液压阀，其中壳体（1）至少并且还优选地布置在内部的主控制活塞（3），压力计活塞（6）等操作部件所述壳体（1）并影响液压油流动，由能够硬化和回火的铝合金制成。因此，能够显着地降低高压液压阀的重量。由铝合金制成的可硬化和回火的部件的表面有利地进行阳极氧化，以增加其更高的耐磨性。这种特别重量轻的高压液压阀主要用于移动式液压系统，如移动式起重机，升降平台和挖掘机中使用的液压系统。
