Definition: A pressurizer is a device that increases the pressure within a container or vessel to prevent it from collapsing under the weight of its contents. This helps maintain the integrity and stability of the system, which can be important in various applications such as ship design, rocket engine operation, and medical equipment.
Definition: In physics, a pressure-boosting device that increases the amount of gas or liquid in a container to achieve an increased pressure. This process is often used in aircraft, where it helps to maintain cabin pressure and prevent depressurization during takeoff and landing. The term "pressurizer" can also refer to a type of airbag, which is designed to provide additional pressure when needed by inflating the bag with compressed air.
