Hello Chvijin,

Welcome to the cove.

The crank shaft of a compressor has crank pins to which the big end of con.rods are attached. Displacement of a crank pin from crankshaft is called a 'Throw'. The number of throws may be odd or even and vary from 1 to 16 or more in V shape models.

Hope this helps.

Umang

Throw is related to number of cylinders and you'll normally have a 2-stroke type compressor...intake-compression/exhaust

IMO the 'THROW' of a compressor is directly linked to the 'CRANK THROW'. Copied below is a portion from the website of Dresser-Rand which speaks of crank throws.

The Dresser-Rand HHE reciprocating compressor has earned a reputation of conservative, rugged design with high reliability and flexible operational capabilities. Our HHE compressors provide gas compression to more than 60,000 psi and are suited to drivers ranging from 200 to 22,500 hp (16,778 kW). HHE frame configurations are available with up to ten crank throws. The VB, VG, and VL models have a variable crank design with a bearing between each crank throw so that both odd and even crank throw options are possible. This reduces cost and parasitic horsepower as balancing cylinders with connecting rod and crosshead are not required for on odd throw applications. For your application, we carefully match HHE compressor components to suit your specific requirements. Choosing from among our HHE frame sizes and our many cylinder, valve, distance piece and driver options, we engineer the best combination of components to provide the most reliable, efficient compressor for your needs.

2. Also there are variable capacity compressors having adjustable 'Crank Pin Throw' structure - The compressor includes a reversible motor that rotates a crankshaft. The crankshaft is connected to a piston by a mechanical system. The mechanical system drives the piston at a full stroke between a bottom position and a top dead center position when the motor is operated in a forward direction. The mechanical system drives the piston at a reduced stroke between an intermediate position and the top dead center position when the motor is operated in the reverse direction. The compressor also includes a control for selectively operating the motor in either the forward direction at a first preselected, fixed speed or in the reverse direction at a second preselected fixed speed.

Hope this helps
