Abstract
A brake booster,of tandem type includes a solenoid,within a valve body,. The solenoid,is provided with a forwardly disposed holder,and a rearwardly disposed yoke,, with a spool,held sandwiched therebetween and with a piston,disposed to be moveable around the inner periphery. A tubular guide,A is formed on the front portion of the piston,while an annular guide,B is formed on the rear portion of the piston,. The tubular guide,A is slidably fitted into the inner periphery of the holder,while the annular guide,B is slidably fitted into the inner periphery of the yoke,. When the solenoid,is energized to cause the piston,to move back and forth relative to the holder,and the yoke,, this movement is guided by the both guides,A,,B. This arrangement permits a smooth back-and-forth movement of the piston,as compared with the prior art.
