Document Type and Number:
Japanese Patent JP2015107794
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To accomplish the purpose of taking measures against cavitation, taking measures against a following wake, reducing viscosity resistance, reducing the occurrence of vibromotive force, improving a propulsion speed and pursuing the improvement of quietness, and utilize compressed air as means for the purpose thereof; and to provide a fluid machine for producing compressed air, a gas-liquid mixed fluid machine and a compressed air supply system using the same, and a water jet propulsion apparatus utilizing a gas-liquid mixture supply jet system.SOLUTION: A fluid machine includes a propeller 127 at an upstream side inflow port 107 for air intake, and includes a logarithmic spiral-shaped vane 118 at the subsequent stage thereof and an axial-flow compression mechanism including an axial-flow impeller 101 for compressing air at the further subsequent stage thereof which are installed in series. The fluid machine includes a power shaft 117 for driving the mechanism to cause compressed air to flow downstream. A freely rotatable sloped cylinder 112 which accommodates a twisted impeller 124 and is provided with a slope from a wide diameter to a small diameter is installed to further promote the compression of the inflow compressed air by a volume change effect. By the rotation of the freely rotatable sloped cylinder and the twisted impeller, the highly compressed air is discharged from a discharge port 111 in a state of a swirl vortex flow.
