Abstract:
A pressurizing apparatus comprising a fixed portion, an input shaft for acting directly in an axial direction with respect to the fixed portion, an output shaft extending coaxially with the input shaft to slide with respect to said fixed portion and said input shaft, a direct-connecting mechanism for directly connecting the output shaft and said input shaft and for causing said input shaft to directly act with respect to the fixed portion to thereby rapidly carry said output shaft with respect to the fixed portion, a fluid pressure mechanism for connecting said input shaft and said output shaft in a fluid manner and for causing said input shaft to directly act with respect to said output shaft to thereby increase biasing of said input shaft by Pascal's law and transmit the biasing to said output shaft, and a control mechanism actuated by biasing applied by said input shaft to control fluid connection of said input shaft and said output shaft to each other.
