Abstract

A known electromagnetically actuatable valve has a tubular housing sleeve, a through opening radially penetrating the housing sleeve, and inside the housing sleeve, a valve body having a valve seat and an associated movable valve closing member, and a throttle, which comprises a throttle body and a throttle insert built into it having a throttle restriction, which is embodied as a throttle bore. The throttle body is slipped on like a cap over an open end of the housing sleeve. The throttle of this kind, embodied in a complex manner, is expensive and demands an inordinate amount of installation space. To reduce expense and save installation space, the throttle body along with its throttle insert is omitted and the function of the throttle bore is taken on by the through opening, the through opening is embodied as narrow opening in accordance with the throttle function to be produced. The valve can be used in antilock devices of hydraulic brake systems for motor vehicles.
