What is the purpose of the oil burner coupling?

The purpose of the oil burner coupling is to pass the flow of oil from the oil motor to the fuel pump. This coupling is a critical component in the oil burner system, as it allows for the efficient transfer of fuel needed for combustion. By linking the motor, which powers the system, to the fuel pump, the coupling ensures that the correct amount of oil is delivered through the system for optimal operation of the burner.

In an oil burner setup, the motor typically drives the fuel pump, which then feeds oil to the burner nozzle. The coupling allows this energy transfer to happen smoothly, facilitating a continuous flow of oil. When properly functioning, this mechanism helps maintain the burner’s efficiency and performance by ensuring that the fuel supply remains consistent and reliable.

The other options focus on functions that are not related to the direct mechanical connection of components within the oil burner system, such as oil pressure control or flame regulation. These are important aspects of burner operation but do not pertain specifically to the role of the coupling itself.
