Abstract

PURPOSE:To repeat the increase and decrease of the volume of a space which intervenes in between a piston and a partition board by carrying out the conversion of the rotation of a rotary shaft into the swinging of a swinging shaft which crosses at a right angle with said rotary shaft, by means of a Z-crank. CONSTITUTION:Partition boards 7 which form operating chambers are fixed to an outer cylinder 5 while pistons 6 which are fixed to a swinging shaft 4 and which increase and reduce the volumes of the operating chambers are also provided in the outer cylinder 5. A rotary shaft 1 crosses at a right angle with the swinging shaft 4 to which a swinging frame 3 is fixed in the middle of a Z-crank 2 while the arm of the Z-crank 2 is connected to the swinging frame 3 by means of a pin joint. When the rotary shaft 1 is rotated, the arm of the Z-crank 2, being restricted by the swinging frame 3, swings together with the swinging shaft 4 in a plane which crosses at a right angle with the swinging shaft 4, including the rotary shaft 1. Thereby, the pistons 6 fixed to the swinging shaft 4 swing with respect to the partition boards 7 fixed to the outer cylinder 5, repeating the increase and decrease of the volumes of spaces intervening in between the pistons and partition boards. And, this action can be applied to any of a compressor, a pump, a hydraulic motor, an internal combustion engine, etc.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (1) Purpose of the Invention The present invention is a swinging piston machine used in compressors, pumps, hydraulic motors, internal combustion engines, etc. This is characterized in that the conversion between the swinging motion of the swinging axis orthogonal to this is performed by a Z crank.

(2) Structure and effect of the invention FIG. 1 is an explanatory diagram of a swinging piston machine, and FIG. 2 is an explanatory diagram of a cross section of a piston part. 1 is the rotating shaft, 2 is the Z crank,
3 is a swinging frame, 4 is a swinging shaft, 5 is an outer cylinder, 6 is a piston fixed to the swinging shaft 1, and 7 is a partition plate fixed to the outer cylinder 5.

Axis of rotation! and the swing axis 4 are perpendicular to each other at the center of the Z crank 2.

A swing frame 3 is fixed to a swing shaft 4, and the arm of the Z crank 2 and the swing frame 3 are connected by a pin joint.

When the rotation axis I is rotated, the arm of the Z crank 2 is held by the 11π moving frame 3 and swings together with the swing axis 4 in a plane that includes the rotation axis I and is perpendicular to the swing axis 4.

The piston 6 fixed to the swing shaft 4 swings relative to the partition plate 7 fixed to the outer cylinder 5, and the volume of the space sandwiched between them increases and decreases repeatedly. This operation includes compressors, pumps, hydraulic motors,
It can be used in internal combustion engines, etc.

The number of pistons 6 and partition plates 7 can be appropriately selected in consideration of the swing angle and the thicknesses of pistons 6 and partition plates 7.
