摘要： A drain system for a marine vessel is provided which includes one or more pressure actuated valves associated with the coolant water drain system. The boat operator is provided with a pressure controller that allows pressure to be introduced into the system for the purpose of actuating the drain valves and, as a result, opening various drain conduits to allow cooling water to drain from the engine cooling system into the bilge or overboard.

摘要： An engine cooling system is provided with one or more flexible conduits attached to drain openings of the engine and its related components. First ends of the conduits are attached to the drain openings while the second ends are sealed by studs attached to a plate of a stationary bracket. A retainer is slidably associated with the flexible conduits and attached to a tether which is, in turn, attached to a handle. By manipulating the handle, the tether forces the retainer to slide along the flexible conduits and control the position of second ends of the flexible conduits. This allows the system to be moved from a first position with the second ends of the conduits above the first ends of the conduits to a second position with the second ends of the conduits below the first ends and in the bilge of the boat. The system allows an operator to stand in a single location and move the drain system from the first and second position and back again without having to reach down into the engine compartment to remove drain plugs. The system allows the cooling system to be easily drained or flushed.

摘要： An apparatus for separating solid material from cooling water in the cooling system of a marine engine. The apparatus includes a hollow member or housing having an inlet to receive cooling water and having an outlet. A drain opening is located in the housing above the bottom surface of the housing and is connected through a suitable conduit to a temperature responsive drain valve. A generally J-shaped tubular member is disposed in the housing and has one end connected to the drain outlet while a second end is slightly above the bottom surface of the housing, out of alignment with the inlet. When the drain valve is open, water will drain through the housing to the drain outlet, while solid debris will collect in the bottom of the housing beneath the second end of the tubular member.

摘要： An apparatus for separating solid material from cooling water in the cooling system of the engine block of a marine engine. The engine block comprises a plurality of cylinder bores surrounded by a cooling passage through which cooling water is pumped. The bottom portion of the block includes a drain outlet that communicates with the cooling passage and a tubular separating member has a first generally horizontal section that is sealed within the drain outlet. The tubular separator also includes a second section that is located within the cooling passage and extends downwardly from the inner end of the first section and is located between two adjacent cylinder bores. The lower end of the second section is closed and a port is provided in the side of the second section adjacent the closed end and facing toward one of the cylinder bores. The outer end of the first section of the tubular member, which is located on the exterior of the block, is connected through a suitable hose or conduit to an automatic drain valve which is located at a level beneath the engine block. When the ambient temperature falls beneath a selected value, the drain valve will open and water will drain from the engine block through the tubular separator to the drain valve, while solid debris will collect in the bottom of the cooling passage beneath the level of the port to prevent the debris from contacting the temperature responsive valve.

摘要： A flushing system provides a pair of check valves that are used in combination with each other. One of the check valve is attached to a hose located between the circulating pump and the thermostat housing of the engine. The other check valve is attached to a hose through which fresh water is provided. Both check valves prevent flow of water through them unless they are associated together in locking attachment. The check valve attached to the circulating pump hose of the engine directs a stream of water from the hose toward the circulating pump so that the water can then flow through the circulating pump, the engine block, the heads, the intake manifold, and the exhaust system of the engine to remove seawater residue from the internal passages and surfaces of the engine. It is not required that the engine be operated during the flushing operation.

摘要： A drain valve assembly for automatically draining water from a cooling system of an inboard marine engine when the ambient temperature drops to a preselected value. The drain valve includes a cup-shaped base having a group of inlets connected to portions of a cooling system of the engine to be drained, and the open end of the base is enclosed by a cover. Each inlet defines a valve seat and a sealing piston is mounted for movement in the base and includes a series of valve members that are adapted to engage the valve seats. An outlet is provided in the sidewall of the cup-shaped base. The valve members on the sealing piston are biased to a closed position by a coil spring and a temperature responsive element interconnects the sealing piston with the cover. The temperature responsive element is characterized by the ability to exert a force in excess of the spring force of the coil spring when the ambient temperature is above about 50.degree. F., to thereby maintain the valve members in the closed position. When the temperature falls below the selected temperature, the temperature responsive element will retract, thereby permitting the valve members to be opened under the influence of the spring to automatically drain water from the cooling system of the engine.
摘要翻译： 排水阀组件，用于当环境温度下降到预选值时，自动从内侧船用发动机的冷却系统排出水。 排水阀包括杯形基座，其具有连接到待排放的发动机的冷却系统的一部分的入口组，并且基座的开口端由盖包围。 每个入口限定阀座，并且安装密封活塞用于在基座中移动，并且包括适于接合阀座的一系列阀构件。 出口设在杯形底座的侧壁中。 密封活塞上的阀构件通过螺旋弹簧偏压到关闭位置，并且温度响应元件将密封活塞与盖相互连接。 温度响应元件的特征在于当环境温度高于约50°F时施加超过螺旋弹簧的弹簧力的能力，从而将阀构件保持在关闭位置。 当温度低于所选择的温度时，温度响应元件将缩回，从而允许阀构件在弹簧的影响下打开以自动从发动机的冷却系统排出水。

摘要： A draining system for a marine propulsion engine is provided in which a manifold is located at a low portion of the cooling system to allow all of the water within the cooling system to drain through a common location, or manifold. A rigid shaft is connected to a valve associated with the manifold and extended upwardly from the manifold to a location proximate the upper portion of the engine so that a marine vessel operator can easily reach the upper end of the shaft and manipulate the shaft to open the valve of the manifold. In this way, the valve can be opened to allow all of the water to drain from the engine without requiring the marine vessel operator to reach toward locations at the bottom portion of the engine.

摘要： A musical instrument amplifier has all solid state amplification stages but incorporates a pair of vacuum tube signal magnitude limiters to provide vacuum tube type sound when the amplifier is operating in a nonlinear condition. The vacuum tubes are connected to have no supply potential so as to minimize microphonics and are each provided with a small amount of reverse bias to provide a desirable shape of the tube conduction curve and space charge suppression.

摘要： A method for cooling a marine propulsion system directs a portion of a recirculating stream of cooling water to a first port of an exhaust manifold so that a cooling jacket of the exhaust manifold can be maintained in a filled condition. Water flows upwardly through the cooling jacket and exits through a port in the exhaust manifold back into the recirculating stream of cooling water that passes through a recirculation pump, the cooling passage of an engine, and a cavity of a thermostat housing.
