JPS5677569A - Variable capacitance type fluid pressure rotary device - Google Patents

Abstract

PURPOSE: To simplify the structure of the subject device by providing two sets of deaerator type fluid pressure converting parts operating in linkage with each other, and incorporating a rotation changeover part capable of interrupting the supply and exhausting of a fluid with respect to one fluid pressure converting part, between the fluid pressure converting parts.

CONSTITUTION: A rotation changeover valve 24 is provided between fluid pressure converting parts 1A and 1B. This rotation changeover valve 24 comprises a pair of fixed plates 25A and 25B and a rotation changeover valve body 26 clamped by fixed plates 25A and 25B and being rotatable. The rotation changeover valve body 26 is actuated so that it assumes the first and second changeover positions by the operation of a changeover handle 30 which connects a driving lever 27 implantedly provided on the peripheral surface through a link member 28 and a shaft 29. At the first changeover position, there is formed a connecting path which performs the supply and exhaustion of the fluid with respect to the fluid pressure converting part 1B through clearances between the teeth of the fluid pressure converting part 1A. At the second changeover position, the above connectng path is interrupted, and further the inter-teeth clearances of the fluid pressure converting part 1B are mutually communicated with each other.
