Should the shut off valves on the rear of the last trailer be opened or closed?
Closed
What is cams on a car?
Camshaft opens and closes the valves The CAMSHAFT is connected to the CRANKSHAFT with gears so that the valves (intake and exhaust valves) are opened and closed at the proper time for each cylinder, and fully sychronized for with the movement of all of the other parts of the engine.
What is the definition of reciprocating pump?
a pump consisting of a piston that moves back and forth or up and down in a cylinder. The cylinder is equipped with inlet (suction) and outlet( discharge) valves. On the intake stroke, the suction valves are opened, and fluid is drawn into the cylinder. On the discharge stroke, the suction valves close, the discharge valves open, and fluid is forced out of the cylinder.
Which heart valve is open under pressure?
When the atria contract, there is increase in pressure in the atrial chambers. So both bicuspid and tricuspid valves opened up. When both the ventricles contract, both the bicuspid and tricuspid valves get closed. This opens up the aortic and pulmonary valves.
Function of valve?

What is a valve spring and where is it located on an engine?
The valve springs hold the inlet and exhaust valves shut, so that compression can take place in the cylinder. Most valves are called 'poppet' valves and look like a mushroom. The spring fits around the valve stem and attached at the top by a disc and collets. The valves are opened against the spring tension, by the camshaft lobes, either directly or by push rods. On most engines the valves and springs are on top of the engine, under a tin or aluminum cover. Older 'side valve', 'flat head' engines have the valves at the side of the engine block. Not much can be done to valves, or springs, without first removing the cylinder head. The valve has to be accessed on both sides, in order to release the spring.
