A discharge-pressure reduction unit reduces the discharge pressure of a charge pump.
discharge pressure from the working pump
The discharge pressure detection means (500) detects the pressure of refrigerant in a high-pressure region.
A variable discharge hydraulic pump (44) supplies operating oil to the hydraulic cylinders (48), and the discharge pressure does not follow the load pressure.
In one embodiment, discharge pressure control can reduce the cooling capacity without increasing the compressor pressure ratio or discharge temperature.
The use of natural gas in accordance with its delivery pressure is particularly advantageous.
During operation, the delivery pressure in a pressure chamber (16) ensures application of the pump components.
The ECU (100) is preferably operative to provide a selected delivery pressure to the brake chamber without measurement of delivery pressure to the brake chamber.(14, 16).
Said passage (28, 30, 32, 34) is automatically opened against the elastic force when a defined delivery pressure is exceeded and the elastic element automatically closes the passage (28, 30, 32, 34) below a defined delivery pressure.
According to the invention, the gas bearing is a self-sufficient bearing, in which the supply pressure is independent of the delivery pressure.
absolute outlet pressure at pump outlet (kPa
The inventive piston pump (10) has the advantage of being better able to build up pressure when the displacement pressure is low at the beginning of a displacement.
The system has a head pipe (12) to impart head pressure to the slurry.
The orifice relieves backpressure within the compression cylinder.
The pressure valve (24) and the dispensing valve (30) can be moved by the feeding pressure and the suction valve (16) can be moved by pressure differentials and by mechanical forces.
Initial pressure up to 13 bar – discharge pressure up to 45 bar
Initial pressure up to 13 bar – discharge pressure up to 45 bar
Initial pressure up to 13 bar – final pressure up to 45 bar
Initial pressure up to 13 bar – final pressure up to 45 bar
3, discharge pressure and speed has nothing to do, low flow can also maintain a high discharge pressure.
The second regulating valve (29a) is monitored based on a discharge pressure setpoint (32) for modifying the discharge pressure of the secondary pump (9) thereby adapting its selective pumping capacity.
Accordingly, the rotation and stoppage of rotation of the cam ring is accomplished based on changes in the discharge pressure, to enable variation in discharge volumes, and enhancement of discharge efficiency.
The device performs measuring of venous pressure, pulmonary pressure, bladder pressure, or intracranial pressure without significant head pressure artifact and with a sufficient dynamic response.
A governor varies the rpms of the engine in response to pressure changes detected by the discharge pressure sensor.
The conveyor pressure is generated by a piston-cylinder system (1) in a pressure-sealed working chamber (12).
