ABSTRACT:
In an electro-mechanical converter of the type wherein a plunger contained in a cylinder is moved in the axial direction thereof by passing a control signal through a solenoid coil wound about the cylinder, the diameter of the plunger is made sufficiently smaller than the inner diameter of the cylinder such that the plunger can move without causing undue friction. The plunger is supported by ball bearings to be movable with respect to the cylinder. To control a power steering unit of a motor car a control valve is actuated by the plunger for controlling the amount or pressure of the operating oil supplied to the power steering unit, in which case the control signal is made to be proportional to the speed of the motor car.
