CONSTANT PRESSURE CONTROLLER (CPR)
Constant pressure controller is used to maintain constant pressure at the outlet of screw type oil pump.
Principle of operation: The upstream pressure that is to be controlled is transmitted to the metal bellow actuator and converted into positioning force which is used to adjust the opening of CPR according to the stiffness of the spring.

FLOW REGULATORS
Flow regulator is used to regulate the oil flow to the turbo generator shaft seal.
Principle of operation: Position of plug and restriction provided in the regulator controls the rate of flow. For flow control, the high pressure oil is transmitted to the high pressure side of actuator diaphragm via control line. The low pressure is transmitted via a hole in the plug to the low pressure side of diaphragm.
The differential of these high and low pressure is converted into positioning force. This positioning force is used to adjust the position of plug and thereby regulating the oil flow.
