JPS5853202B2 - pure fluid element - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pure fluid element that stabilizes fluid control operation by providing a rectifying member at a fluid control port and has a smaller element shape.

In conventional pure fluid devices, a throat portion of a certain length is provided at the supply port for the purpose of stabilizing fluid control operation.

However, with this configuration, the overall length of the element becomes larger by the length of the throat portion, resulting in a problem that the fluid equipment in which the pure fluid element is incorporated becomes larger.

The present invention solves the above conventional problems by providing a flow regulating member at the supply port and using this filter to make the flow velocity distribution uniform.Examples thereof will be described below with reference to the accompanying drawings.

In Fig. 1, 1 is a supply port 2, fluid adhesion walls 3 on both sides,
3', and control ports 5, 5' opened in the fluid-proof walls 3, 3', respectively. The element body is equipped with a fluid rectifying member 6 made of a porous material or the like, and when the fluid passes through the rectifying member 6, the resistance equalizes the flow velocity distribution and the fluid is ejected to the output port 4.

Now, when one control port 5 is closed by the closing means 7,
The fluid adheres to the corresponding fluid adhering wall 3, and the flow of the fluid is eventually deflected toward this wall 3.

When the opposite control port 5' is closed, fluid adheres to the wall 3' and the flow is switched in the same direction.

In this way, in this pure flow element, the function of equalizing the fluid velocity distribution in the throat part of the conventional one is performed by the rectifying member 6, and therefore the element length is shortened by an amount equivalent to the length of the conventional throw 1. It is possible.

Figure 2 shows an example of an air conditioner in which heat is exchanged with a heat exchanger 8 and the blowing direction of conditioned air sent out via a fan motor 9 is changed by the above-mentioned pure fluid element. The short length allows the entire fuselage to be compact, and the air outlet does not protrude beyond the fuselage, which would be unsightly.

Since the present invention is provided with a liquid rectifying member at the supply port, a part of the slot for equalizing the fluid velocity distribution is not required, and since this rectifying member is placed close to the supply port, the result is As a result, the overall size can be made extremely small.
