Patent JP-S57171096-A (JP)
Title: Ventilator
Inventor: SUGAWARA NORIO
IPC: F24F13/14
Filed: 1981-04-15
Abstract: PURPOSE:To enable to divide air flow produced by a cross-flow fan into a downward  stream and a horizontal stream at a desired air flow dividing rate, by providing a  flow control member for deflecting the air flow produced by vortices toward a downstream side of a rear guide in the manner that air flows along the downstream part of  the rear guide. CONSTITUTION:When a cross-flow fan 7 is turned, vortices V are produced and air  flow is produced by the vortices V. A rear guide 9 consists of an upstream member 9a  and a downstream member 9b that is turned pivotally around a pin 10. By turning the  member 9b, the position of the vortices V is shifted around the center of a fan shaft  70. In case that the angle of the rear guide 9b is smaller than about 60 deg., air flow is  divided by a control member 11. Here, air flow Fa between the control member 11 and  a stabilizer 8 tends to discharge horizontally by the function of the vortices V. However, as the angle theta of the rear guide 9b is increased gradually to 60 deg., the deflection  angle alpha is substantially in the horizontal direction. Further, when angle theta is 90 deg., the deflection angle alpha is directed substantially downward, as can be seen from the drawing. That is, the direction of air flow can be changed by the function of shifting of the  vortices as well as the tendency of air flow itself to stick to the surface of the rear guide.

IPC: F04B27/18
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To restrict a reverse flow of a liquid refrigerant to a compressor from a condenser, etc., on a high pressure passage, and prevent pressure in the compressor from being abnormarily increased by providing on a high pressure passage communicating between a discharge region of the compressor and an expansion valve opening/ closing means for opening/closing the high pressure passage, and disposing a relief valve on an upstream side from the opening/closing means. SOLUTION: A check valve 101 is provided at a connection part between an outlet of a discharge muffler 74 of a clutchless single head inclined variable capacity compressor 22 and a high pressure passage. With the check valve 101 a reverse flow of a liquid refrigerant from the high pressure passage to the discharge muffler 74, and hence only discharge of compressed refrigerant gas from the discharge muffler 74 to the high pressure passage is allowed.  A relief valve 108 is screwed into a screw hole of a mounting hole 105 formed in the discharge muffler 74, and hence even when the check valve 101 closes the high pressure passage and hence the inside of the compressor 22 becomes an abnormal high pressure state, pressure in the compressor 22 can be released to the outside of a freezing circuit through the relief valve 108, and thus there is securely eliminated a fear that pressure in the compressor 22 is increased above a predetermined value.
