A bilge pump is a water pump used to remove bilge water. Since fuel can be present in the bilge, electric bilge pumps are designed to not cause sparks. Electric bilge pumps are often fitted with float switches which turn on the pump when the bilge fills to a set level. Since bilge pumps can fail, use of a backup pump is often advised. The ...
A "4-way" (intermediate) switch is a purpose built double pole, double throw (DPDT) switch, internally wired in manufacture to reverse the connections between the input and output and having only four external terminals. This switch has two pairs of "traveler" terminals that it connects either straight through, or crossed over (transposed, or ...
A white box system is a mechanical system installed in the engine room of a ship for controlling and monitoring the engine room bilge water discharge from the vessel. The system consists of all vital components for monitoring and controlling the discharge from the vessel's oily water separator. The white box includes a stainless steel cage with ...

Bilge water is a nearly-unavoidable byproduct of shipboard operations. Oil leaks from running machinery such as diesel generators, air compressors, and the main propulsion engine. Modern OWSs have alarms and automatic closure devices which are activated when the oil storage content of the waste water exceeds a certain limit(15ppm : 15 cm3 of ...
The limber holes allow water to drain into the lowest part of the bilge so that it can be pumped out by a single bilge pump [1] (or more usually, one electric and one manual pump). The term is also commonly applied to the holes in mid-20th century submarine upperworks, which allow drainage from the superstructure. [2]
A toggle light switch Internal components of a toggle switch. The toggle mechanism provides "snap-action" through the use of an "over-center" geometry. The design was patented in 1916 by William J. Newton and Morris Goldberg. [2] The switch actuator does not control the contacts directly, but through an intermediate arrangement of springs and ...
The ratio is determined by the ratio of the distances from the rocker arm's pivot point to the point where it touches the valve and the point where it touches the pushrod/camshaft. A rocker ratio greater than one essentially increases the camshaft's lift. Current automotive design favors rocker arm ratios of about 1.5:1 to 1.8:1.
