Abstract (en)

[origin: DE19802464A1] A magnetically operated (14,16) hydraulic valve forming part of a vehicular brake system has a valve housing (11) with a guide body (13) for the hydraulic fluid. The guide body is positioned between the valve body (12) with a hollow spherical valve seat (26) and the valve housing chamber (21). The guide body redirects fluid emerging from the valve seat into an annular passage so that any unstable flow is without effect on the valve (10) chamber.
