Abstract
Fluid equipment includes a container configured for having first and second fluids therein, a first fluid outlet/inlet path provided for outflow and inflow of the first fluid, a second fluid outlet/inlet path for outflow and inflow of the second fluid, and a member configured for moving in the container in response to pressure of the first fluid, the fluid equipment transmitting energy from the first to the second fluid. A first bellows is configured such that one end is closed in a sealed state by the moving member, the other end is fixed to an inner surface part of the container in a sealed state, and the inside of the first bellows communicates with the first fluid outlet/outlet path.
Claims20
1:
- Fluid equipment comprising a container configured for having a first fluid and a second fluid housed therein, a first fluid outlet/inlet path provided at the container for outflow and inflow of the first fluid, a second fluid outlet/inlet path provided at the container for outflow and inflow of the second fluid, and a moving member configured for moving in the container in response to a pressure of the first fluid, the fluid equipment transmitting energy from the first fluid to the second fluid,
- the fluid equipment further comprising a first bellows configured for expanding and contracting
- the first bellows having a first end portion closed in a sealed state by the moving member and a second end portion fixed to a first inner surface part of the container in a sealed state,
