Abstract

A fluid heating device includes a pressurizing chamber configured to store a working fluid and a heat accumulator disposed in the pressurizing chamber. The heat accumulator includes a heat accumulating member configured to release heat by receiving a pressure applied to the working fluid. The fluid heating device has improved actuation efficiency.

First claim

The invention claimed is:

1. A fluid heating device, comprising:
a pressurizing chamber configured to store a working fluid; and
a heat accumulator disposed in the pressurizing chamber, wherein:
the heat accumulator includes a heat accumulating member configured to release heat by receiving a pressure applied to the working fluid,
the heat thus released is given to the working fluid,
the heat accumulating member includes substitutional trititanium pentoxide, and
a substitutional atom in the substitutional trititanium pentoxide is at least one kind of atoms selected from the group consisting of Hf, Zr, Si, Sc, and Y.

2. The fluid heating device of claim 1 , further comprising a pressurizing device configured to apply a pressure to the working fluid.

3. The fluid heating device of claim 1 ,
the heat accumulating member is configured to absorb heat from the working fluid.

4. The fluid heating device of claim 1 , wherein
the working fluid includes fuel to be supplied to a combustion device.

5. The fluid heating device of claim 1 , further comprising a hollow member in which the pressurizing chamber is formed, wherein
the heat accumulator is provided to an inner peripheral surface of the hollow member.

6. The fluid heating device of claim 1 , wherein
the heat accumulating member is in bulk form.

7. The fluid heating device of claim 1 , wherein
the heat accumulator includes a plurality of the heat accumulating members, and
each of the plurality of heat accumulating members is in granular form.

8. The fluid heating device of claim 1 , wherein
the heat accumulating member is in mesh form.

9. The fluid heating device of claim 1 , wherein
the heat accumulating member is a porous member.

10. The fluid heating device of claim 1 , wherein
the heat accumulating member is movable within the pressurizing chamber.

11. The fluid heating device of claim 1 , wherein
the pressurizing chamber includes a common rail.

12. A motor system, comprising:
the fluid heating device of claim 1 ; and
an internal-combustion engine to which the working fluid is supplied.

13. A movable object, comprising
the motor system of claim 12 ,
wherein the movable object is configured to be movable by using, as power, mechanical energy obtained from the internal-combustion engine.

14. A hydraulic system, comprising
the fluid heating device of claim 1 ,
wherein the working fluid is a hydraulic oil.
