Title:
FLUID MACHINE
Document Type and Number:
Japanese Patent JPS61160501
Kind Code:
A
Abstract:
PURPOSE:To make it possible to obtain a high degree of mechanical efficiency with a simple structure, by obtaining discharge force or torque from the reciprocating motion of a piston disposed in a through-hole which is formed in a cylinder block rotated in association with the rotation of a journalled drive shaft. CONSTITUTION:In an air-compressor, when a drive shaft 5 is rotated, a rotary disc 23 is rotated by means of a gear cylinder 4. This rotation rotates a driven shaft 18 through helical bevel gears 4A, 18A so that a cylinder block 12 is also rotated. When the cylinder block 12 and the rotary dick 23 are rotated in synchronization with each other, a piston 15 positioned in the vicinity of a low pressure side passage 3B moves toward its bottom dead center while a piston positioned in the vicinity of a high pressure side passage 3D is moved toward its top dead center. When the pressure of the high pressured side passage 3D becomes high, a float valve 21 is pressed against the end face of the cylinder block 12 so that a through-hole 11 is hermetically closed by itself.
