摘要： An improved flow control mechanism for a tilt and trim adjustment systern quickens tilt operation of an associated outboard drive, without sacrificing a desired control when trimming the outboard drive. The flow control mechanism includes a bypass line that interconnects the two sides of a respective tilt and trim cylinder. A bypass valve regulates flow through the bypass line. The bypass valve opens the bypass line when moving the outboard drive within the tilt range to quicken this operation. When moving the outboard drive within the trim range, however, the bypass valve closes the bypass line and connects an up chamber of the cylinder to a suction side of the pump to slow the speed at which the tilt and trim adjustment systern moves the outboard drive within this range of movement. The slower speed by which the systern raises and lowers the outboard drive enhances the ability to control the adjustment of the outboard drive's trim position. An actuator mechanism automatically controls the valve depending upon whether the drive's movement occurs within the tilt range or the trim range.
摘要翻译：用于倾斜和调整调整系统的改进的流量控制机构加快了相关联的外侧驱动器的倾斜操作，而在修剪外侧驱动器时不牺牲期望的控制。流量控制机构包括将相应的倾斜和装饰缸的两侧相互连接的旁通管线。旁路阀调节通过旁路管路的流量。在倾斜范围内移动舷外驱动器时，旁路阀打开旁路管路，以加快此操作。然而，当外侧驱动器在调整范围内移动时，旁通阀关闭旁路管路，并将气缸的上升室连接到泵的吸入侧，以减慢倾斜和调整调整系统移动舷外驱动器的速度在这个范围内的运动。系统提升和降低外侧驱动的较慢速度增强了控制舷外机驱动装置位置调整的能力。执行器机构根据驱动器的运动是否发生在倾斜范围或修剪范围内自动控制阀。

摘要： A conduit arrangement in a hydraulic tilting system for an outboard drive unit wherein a plurality of connecting members are provided, one mounted at the lower end of the gimbal housing and two mounted on the outer periphery of the gimbal housing higher than the upper connecting member but lower than the tilt shaft on the gimbal ring. A pair of inboard conduits extend from a pressure source within the hull of the associated marine vessel to the lower connecting member while two pairs of intermediate conduits interconnect the lower connecting member with a respective one of the upper connecting members. There are two pairs of outboard conduits, each pair interconnecting one of the upper connecting members with a respective one of a pair of fluid motors which extend between the gimbal ring and the outdrive portion of the drive unit for effecting tilting and trimming movement of the outdrive. Each of the outboard hoses extend downward and outward from its corresponding upper connecting member to its associated fluid motor. The connecting members are situated to be easily accessible by hand for installation and servicing of the conduits, and the outboard conduits are arranged and configured to improve durability and so as not to interfere with other components.

摘要： This invention primarily relates to an electrical anticorrosion device for a marine propulsion arrangement. More particularly, the invention relates to a cathodic protection arrangement which is suitable for use with an inboard/outboard propulsion unit. According to the invention, an anode and a reference electrode are housed within a housing unit which is mounted upon a propulsion unit mounting bracket. The two electrodes are arranged so that each is essentially equidistant from a point located approximately midway across the lateral width of an outboard drive unit, which unit is secured to the mounting bracket, when the unit is positioned for driving the associated watercraft in a generally forward direction. The electrode housing further serves as a low speed/idle exhaust gas device which breaks up exhaust gas bubbles which otherwise might cause loud and objectionable noise. Thus, the invention allows for the effective prevention of cathodic corrosion by insuring that a proper current is supplied to a sacrificial anode and, additionally, allows for improved silencing for the low speed/idling exhaust gases of an inboard/outboard drive unit.

摘要： Several embodiments of reference electrode constructions for use in electrically anti-corrosion protection systems for marine outboard drives. In each embodiment the reference electrode is contained within a protective covering with a restricted small volume area surrounding the reference electrode. As a result, when the reference electrode dissolves in the body of water in which it is operating it will form a saturated solution in this small volume area to preclude further dissolution.
