Question: 1 / 1030

What does an orifice check valve do in an aircraft hydraulic system?

Increases fluid pressure

Allows fluid to flow freely in one direction and restricts flow in the other

An orifice check valve in an aircraft hydraulic system allows fluid to flow freely in one direction while restricting flow in the opposite direction. This is essential for maintaining proper pressure levels and controlling the direction of fluid movement within the system.

Option A (Increases fluid pressure) is not correct because the primary function of an orifice check valve is not to increase fluid pressure.

Option C (Filters the hydraulic fluid) is incorrect as the main purpose of an orifice check valve is not to filter the hydraulic fluid but to regulate its flow.

Option D (Cools the hydraulic fluid) is also incorrect as orifice check valves do not serve the function of cooling the hydraulic fluid; that task is typically performed by a separate component such as a heat exchanger.
