Abstract
A pump, electromagnetically operable valves and at least one low-pressure accumulator are arranged in a valve block. The valve actuators are disposed in front of a base of the valve block opposite to an electric motor which drives the pump. The housing of the low-pressure accumulator is formed of an add-on piece which is deepdrawn from sheet metal in a bowl-type configuration. The edge of the add-on piece is attached in the mouth of a blind-end bore in the valve block. The add-on piece projects beyond the and has roughly the same height as the actuators of the valves. The actuators and the add-on pieces are covered by a housing cap on the valve block which protects them against environmental influences. The arrangement is extremely compact and permits achieving a relatively small and, thus, light-weight valve block.
