Abstract

A shockwave supply device includes: a shockwave generating unit configured to generate a shockwave; a shockwave emitting unit configured to emit the shockwave; a conduit that is bendable and is provided at a part of a flow path of the shockwave from the shockwave generating unit to the shockwave emitting unit; a plurality of outer shell tubes provided outward in a radial direction of the conduit and provided along an axial direction of the conduit; and a coupling portion with which adjacent ones of the outer shell tubes are coupled to be rotatable with respect to each other about a vertical axis.

First claim

1 . A shockwave supply device comprising:
a shockwave generating unit configured to generate a shockwave; a shockwave emitting unit configured to emit the shockwave; a conduit that is bendable and is provided at a part of a flow path of the shockwave from the shockwave generating unit to the shockwave emitting unit; a plurality of outer shell tubes provided outward in a radial direction of the conduit and provided along an axial direction of the conduit; and a coupling portion with which adjacent ones of the outer shell tubes are coupled to be rotatable with respect to each other about a vertical axis.

2 . A shockwave supply device comprising:
a shockwave generating unit configured to generate a shockwave; a shockwave emitting unit that is connected to the shockwave generating unit and is configured to emit the shockwave; a conduit that is bendable and is provided in a part of a flow path of fuel from a fuel supply source of the fuel supplied to the shockwave generating unit to the shockwave generating unit; a plurality of outer shell tubes provided outward in a radial direction of the conduit and provided along an axial direction of the conduit; and a coupling portion with which adjacent ones of the outer shell tubes are coupled to be rotatable with respect to each other about a vertical axis.

3 . The shockwave supply device according to claim 1 , wherein the outer shell tubes each have an inner peripheral surface provided to face and to be separated from an outer peripheral surface of the conduit.

4 . The shockwave supply device according to claim 2 , wherein the outer shell tubes each have an inner peripheral surface provided to face and to be separated from an outer peripheral surface of the conduit.

5 . The shockwave supply device according to claim 1 , further comprising a position adjustment mechanism that moves the shockwave generating unit, the shockwave emitting unit, and the outer shell tubes in the axial direction of the conduit.

6 . The shockwave supply device according to claim 2 , further comprising a position adjustment mechanism that moves the shockwave generating unit, the shockwave emitting unit, and the outer shell tubes in the axial direction of the conduit.

7 . The shockwave supply device according to claim 5 , wherein the position adjustment mechanism includes racks provided to the outer shell tubes along the axial direction, and a pinion that is rotatable about the vertical axis while meshing with the racks.

8 . The shockwave supply device according to claim 6 , wherein the position adjustment mechanism includes racks provided to the outer shell tubes along the axial direction, and a pinion that is rotatable about the vertical axis while meshing with the racks.

9 . The shockwave supply device according to claim 1 , further comprising an emission direction adjustment mechanism configured to adjust a direction of orientation of an emission port through which the shockwave is emitted from the shockwave emitting unit.

10 . The shockwave supply device according to claim 2 , further comprising an emission direction adjustment mechanism configured to adjust a direction of orientation of an emission port through which the shockwave is emitted from the shockwave emitting unit.

11 . The shockwave supply device according to claim 9 , wherein the emission direction adjustment mechanism is capable of adjusting a length of a side edge in parallel with the axial direction of the conduit in plan view.

12 . The shockwave supply device according to claim 10 , wherein the emission direction adjustment mechanism is capable of adjusting a length of a side edge in parallel with the axial direction of the conduit in plan view.

13 . The shockwave supply device according to claim 1 , wherein the shockwave emitting unit includes an image capturing unit configured to capture an image in a direction of orientation of the emission port through which the shockwave is emitted.

14 . The shockwave supply device according to claim 2 , wherein the shockwave emitting unit includes an image capturing unit configured to capture an image in a direction of orientation of the emission port through which the shockwave is emitted.
