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 gasket for an exhaust system comprises a metallic plate having an exhaust sealing segment and a coolant sealing segment which is attached to and extends from the exhaust sealing segment. Both segments have first and second planar surfaces on opposite sides thereof, with the first and second planar surfaces of the exhaust sealing segment being co-planar with the first and second planar surfaces of the coolant sealing segment, respectively. An exhaust opening is formed through the plate and first and second elastomeric seals, which can be silicone rubber and which are both integral parts of a common elastomeric element, are disposed on the first and second surfaces, respectively, of the coolant sealing segment. A raised portion of the exhaust opening through the metal plate extends at an angle from the exhaust sealing segment and away from the first surface to form a transition segment from a first opening to a second. A hole can be formed through the plate and located at a central region of the coolant sealing segment with the common elastomeric element extending through the hole with the first and second elastomeric seals being joined to each other within the hole. A central portion of the coolant sealing segments can either comprise a hole to allow liquid to flow through the thickness of the plate, or alternatively, can comprise a solid portion that inhibits a flow of liquid through the thickness of the plate.

摘要： A marine engine cooling system is provided with a valve in which a ball moves freely within a cavity formed within the valve. Pressurized water, from a sea pump, causes the ball to block fluid flow through the cavity and forces pumped water to flow through a preferred conduit which may include a heat exchanger. When the sea pump is inoperative, the ball moves downward within the cavity to unblock a drain passage and allow water to drain from the heat generating components of the marine engine.

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： 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： The present invention provides a relationship between the exhaust passages and coolant passages of the exhaust manifold and exhaust elbow which serves to maintain the joint of the exhaust passage at a higher temperature than would be possible with known exhaust manifolds and exhaust elbows. By providing a space between surfaces of a raised exhaust portion of the components and surfaces of the raised coolant portions of the exhaust system, leakage from the coolant conduits to the exhaust cavities is avoided. The space provided between exhaust portions of the manifold and elbow and coolant portions of the manifold and elbow, near the joint between these components, provides the two advantages of maintaining a higher exhaust connection between the manifold and elbow and also preventing coolant leakage from flowing from the coolant passages to the exhaust passages of the exhaust system.
