Typical horizontal steam engine with double-acting cylinder. A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. . In order to connect the piston in a double-acting cylinder to an external mechanism, such as a crank shaft, a hole must be provided in one end of the cylinder for the piston rod, and this is fitted with a gland or ...
Pneumatic telescoping cylinder 5-stage, double-acting, demonstrating full extension and retraction. A double acting cylinder is extended and retracted using hydraulic or pneumatic pressure in both directions. Double acting telescopic cylinders are thus much more complex in design than the single acting type.
The hydraulic cylinders on this excavator operate the machine's linkages. Hydraulic cylinders in a hot press of a particle board machine. A hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke.

A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.
The following diagram shows the relation between the angle of the crankshaft and the delivery rate of a single-acting and double-acting pump. The line shows the average delivery rate of the pump. These fluctuations in pressure and delivery can cause undesired effects such as water hammer and thus are generally mitigated by the installation of ...
Double-acting reciprocating pump engage with both sides of the piston, each stroke of the piston carries out both suction and expulsion at the same time. Thus it require two inflow pipes and two outflow pipes. [2] Triple-acting reciprocating pump; By Numbers of Cylinders. Single cylinder - consists of a single cylinder connected to a shaft.
Cylinder phasing: With two-cylinder compounds used in railway work, the pistons are connected to the cranks as with a two-cylinder simple at 90° out-of-phase with each other (quartered). When the double-expansion group is duplicated, producing a 4-cylinder compound, the individual pistons within the group are usually balanced at 180°, the ...
