Device for Choking a Fluid Flow and Corresponding Piston Pump for Delivering Fluids |
| 摘要 |
A device for choking a fluid flow, with a pot-like base body, in the base of which a first passage opening is arranged, and a closing body guided axially moveably in the pot-like base body against a spring force of a spring element and having a second passage opening that forms a static choke point with a predefined fixed opening cross section. The closing body in combination with the spring element and the first passage opening forms a dynamic choke point with a dynamic opening cross section that is variably adjustable depending on a pressure difference. |

1. A device for choking a fluid flow, comprising:
a pot-like base body including a base having a first passage opening; a spring element; a closing body guided axially moveably in the pot-like base body against a spring force of the spring element and having a second passage opening configured to form a static choke point with a predefined fixed opening cross section; a delay device configured to delay a closing movement of the closing body in a targeted fashion, wherein the closing body in combination with the spring element and the first passage opening forms a dynamic choke point with a dynamic opening cross section that is variably adjustable depending on a pressure difference. |
