<p>According to an embodiment of the present invention, a pumping apparatus for an electrohydraulic power steering includes: a valve; an elastic member configured to operate the valve by generating pressure; a valve guide configured to insert the elastic member, having a plurality of gaps formed therearound, and having a convex side surface; and a housing having a guide seating groove where the valve guide is seated. Thus, a plurality of curved surfaces are formed to stably seat the valve guide on the surface of the housing to maintain the valve guide centered, thereby disallowing the valve guide to be obliquely moved and caught. As a result, an occurrence of vibration may be prevented.</p> |
