Title: Automatically blowing medium voltage breaker
Inventor: DOUNI DEYUFURUNE
IPC: H01H33/91
Filed: 1990-08-16
Abstract: PURPOSE: To form a means for automatically circulate gas between first and second volumes when high intensity breaking current reaches the specified threshold value, use a semi-fixed contact as a pipe for communicating with a third volume, and circulate gas so as to enhance the dielectric quality of gas when the breaking current reaches the upper limit value. CONSTITUTION: When current intensity is higher than a threshold value, while current is maximum, a semi-fixed contact 4 and a piston 8 are moved upward by pressure increase within a volume V1, the piston jumps over an opening 13, the volume V1 communicates with a volume V2. At that time, the pressure in the Volume V1 is higher than that in the volume V2, and a valve 20 is closed. When current is decreased toward zero, pressure in the volume V1 is decreased, the piston 8 is moved downward, the volume V2 is separated from the volume V1. When the pressure in the volume V1 is lowered than that in the volume V2, the valve 20 is opened, gas in the volume V2 is transferred to the volume V1, and gas is contributed to splay to an arc. Since hot gas in the volume V2 goes in from the opening 13 and goes out of the valve 20, gas is circulated.

Title: Ball valve device
Inventor: KUSHIYAMA TADASHI
IPC: F16K17/04
Filed: 1982-12-10
Abstract: PURPOSE:To absorb a small variation in fluid pressure at an inlet of a valve seat for stabilizing operation by providing a minimum throttling portion of a fluid path until a ball is opened and then reaches the maximum lifting position. CONSTITUTION:A side wall 4'a is constituted close to a ball 2' such that a path 8b formed of the ball 2' and side wall 4a' of a ball valve V1' provides a minimum throttling portion of fluid path until the ball 2' is opened and then reaches the maximum lifting position. As the displacement of the ball 2' becomes large, area of a path 8a is enlarged and area of the fluid path 8b is reduced so that pressure in an inlet 1 will act on the whole section of the ball 2'. Thus, when differential pressures in the inlet 1 and the ball chamber 4' are equal, a force pushing up the ball 2' becomes larger than that when the ball 2' is closed. That is, as shown by the curve B, the ball 2' is not operated even when the pressures in the inlet 1 and ball chamber 4' vary somewhat after the ball 2' is completely opened.
