Abstract

PURPOSE: To enable flow compensation due to intake/discharge pressure by contructing the subject valve in such a way that low intake pressure expands a bellows to press in a plug and open an opening so as to reduce compression capacity, on the contrary, high intake pressure closes the opening to make the compression capacity maximum.
CONSTITUTION: When an intake pressure is low, also the pressure in a first chamber 43 becomes low via an induction passage, a bellows 52 is expanded to press in a plug 50 to open an opening, fluid in a cylinder is passed through a second induction passage, a second chamber 44, an opening 42 and the first chamber 43 and flows in an intake chamber to open a bypass hole and compression capacity is reduced thereby. Meantime, when the intake pressure becomes high, the bellows 52 is contracted, the plug 50 closes the opening 42 due to urging force of a spring 51, the pressure in the cylinder rises to close the bypass hole, bypass between a fluid pocket and the intake chamber is not conducted to make the compression capacity maximum. Discharge pressure is introduced in a third chamber 46, back pressure is operated by a rod 54 to vary the compression capacity according to the discharge pressure. Thus, flow compensation can be carried out due to intake pressure and discharge pressure with a simple structure.
