Embodiment Construction

[0019] as from Figure 1 to Figure 3 As can be seen, the illustrated embodiment of the device 10, 10A for throttling a fluid flow according to the invention comprises: a basin-shaped base body 14, in the bottom of which a first through-hole 14.1 is arranged; and Closing body 16, 16A, which is movably guided axially against the spring force of spring element 18, 18A in basin-shaped base body 14, has a second through-hole 16.1 formed with a pre- Static throttle point 11 of defined fixed opening cross-section. The closing body 16 , 16A in combination with the spring element 18 , 18A and the first through-opening 14 . 1 forms a dynamic throttle point 12 , 12A with a dynamic opening cross section which can be variably changed depending on the pressure difference. adjust. According to the invention, a delay device 20 , 20A is provided which delays the closing movement of the closing body 16 , 16A in a targeted manner.

[0020] In the example shown, a throttling device 10 , 10A fo...

Abstract

A device for choking a fluid flow includes 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.

Description

technical field [0001] The invention relates to a device for throttling a fluid flow, with a basin-shaped base body, in the bottom of which a first through-hole is arranged; and an axially counteracting spring element. Closing body that can be guided movably in the pot-shaped base body by the elastic force, said closing body has a second through-opening, which forms a static throttle point with a predetermined fixed opening cross-section , wherein the closing body, in combination with the spring element and the first through-hole, forms a dynamic throttle point with a dynamic opening cross section that can be variably adjusted as a function of the pressure difference. The invention also relates to a piston pump for conveying fluids with such a throttle device. Background technique [0002] Piston pumps for conveying pressure medium in hydraulic brake systems with ABS and / or ESP functions (ABS: anti-lock braking system, ESP: electronic stabilization program). For example, ...
