METHOD AND DEVICE FOR OPERATING A PRESSURE RESERVOIR, IN PARTICULAR FOR COMMON RAIL INJECTION SYSTEMS IN AUTOMOBILE ENGINEERING |
摘要 |
A method and to a device for operating a pressure reservoir, where during a compression phase in a pump chamber, a pump periodically increases the pressure of a fluid located therein, and by means of a discharge valve controlled by differential pressure fluid under high pressure is allowed to be introduced from the pump chamber into the pressure reservoir. During a decompression phase following a compression phase, fluid from a fluid reservoir is introduced into the pump chamber by means of a controllable intake valve. In order to be able also to operate the pressure reservoir without a high pressure measurement directly in the pressure reservoir, the fluid pressure in the pressure reservoir is ascertained by means of a pressure determination in the pump chamber. The pressure determination takes place indirectly, monitoring of the intake valve in the decompression phase. |

1. A method for operating a pressure accumulator, in which method a pump periodically, during a compression phase in a pump chamber, increases the pressure of a fluid situated therein, and fluid at high pressure is admitted from the pump chamber into the pressure accumulator by way of a differential-pressure-controlled discharge valve, and in which method, during a decompression phase following a compression phase, fluid is admitted from a fluid reservoir into the pump chamber by way of a controllable intake valve, comprising the steps of:
determining the fluid pressure in the pressure accumulator by way of a pressure determination in the pump chamber. |
