Flat Single-Acting Hydraulic Cylinder For Marine Use
Definition of Flat Single-Acting Hydraulic Cylinder
A flat single-acting hydraulic cylinder is a specialized component of hydraulic systems designed for efficient power transmission in compact spaces. It is designed to apply force in one direction using hydraulic oil to extend the piston through a spring mechanism or gravity while returning to the original position.
Design and Construction Characteristics
- Flat design allows for use in narrow spaces
- Compact dimensions make it suitable for applications with limited vertical clearance
- Simple operation with fluid pressure applied only to extensions
- Durable materials like high-strength steel and aluminum

Working Principle
The working principle of a flat single-acting hydraulic cylinder is realized by the pressure of hydraulic oil and the action of a spring or gravity to achieve the return. The movement of the piston, input of hydraulic oil, and the repeated cycle contribute to its functionality.
Types and Configurations
There are three different types of flat single-acting hydraulic cylinders, each designed for specific applications. These cylinders offer flexibility, simple operation, durability, and efficient force output.
Advantages
- Space-saving design
- Flexibility in integration
- Simple operation with single-acting mechanism
- Easy maintenance and durability
