Abstract
PURPOSE: To reduce the influence from the pressure change in a blind hole cylinder by providing a sleeve in this cylinder with split grooves for reducing the pressure change in the cylinder.
CONSTITUTION: An end part of a control piston 102 is sealed up by a seal 112, and reciprocated in a blind hole 103. A cylindrical sleeve 120 holding the seal 112 is provided with split grooves 123, and the amount of air in th blind hole 103 is increased by these portions. This construction permits to reduce the change of the air pressure in the blind hole, and minimize the influence given to hydrostatic control.
