Abstract

PURPOSE: To obtain a spool which offers possibility of easy and fast machining, workability under the minimal working pressure, and increase in anti-vibration and anti-impulse in such a way that a hollow pipe which has a good malleability is made plastic deformation in diametral direction, machining can be done easily and fast by partially changing external diameters.
CONSTITUTION: A large diametral part 6' and a small diametral part 7' are obtainable on a spool 2' by effectuating plastic machining in the diametral direction of a pipe. And, since the pipe is used, opening ports 8', 9' at both ends are utilizable for inserting pressured pistons 3, 4 as it is, it can dispense with any need of machining for this purpose. It is recommendable as the material quality to adapt the one which is rich in malleability and compatible for plastic machining, such as aluminum, stainless steel, etc. This facilitates to speed easy machining, to be light in weight because of being hollow, to be able to do with low minimal working pressure, to improve anti-vibration and anti-impulse, and to give longer life.
