Cycling stroke

Re-starting of the pumps or closing of the by-pass valve by reversing the pilot control takes place, when the last but one contact pin is cleared, i. e. after a cycling stroke has been performed as already explained in the operation of the shutoff valve. 

Reciproca.ting Piston Meters. In positive-displacement meters of the reciprocating piston type, one or more pistons similar to those in an internal-combustion engine are used to convey the fluid. Capacity per cycle can be adjusted by changing the piston stroke.

The velocity of the cake is less than the stroke per unit cycle time, the ratio of which is the pushing efficiency. Depenchng on the moisture of the cake as well as the fric tional charac teristics of the screen, a 90 percent efficiency can be attained in proper operation.

Reciprocating engines are available in two basic types—two-stroke or tour-stroke cycle. Regardless of the engine type, the following four f unctions must be performed in the power cylinder of a reciprocating engine ... 

Both two- and four-stroke cycle engines are used in commercial applications. For the purpose of this discussion, however, comments will be limited to applications normally encountered in the oil and gas industry. Some of the advantages and disadvantages associated with each engine type are as follows ... 

Two-stroke cycle machines must be equipped with a scavenge air system that may include a separate scavenge air cylinder, gear-driven blower, or turbochargers. It should be noted, however, that a method must be provided to supply a turbocharged two-stroke cycle engine with air to start.

Both gasoline and diesel engines are available in either a two-stroke- or a four-stroke-cycle design. The fundamental difference between the Otto engine cycle (named after Nikolaus Otto, who developed it in 1876) and the diesel engine cycle involves the conditions of the combustion. In the Otto cycle.
