Description
본 고안은 압전 소자를 이용한 밸브에 관한 것이며, 보다 상세히는 종래의 솔레노이드 밸브를 대체할 압전 소자를 이용한 밸브에 관한 것이다.The present invention relates to a valve using a piezoelectric element, and more particularly to a valve using a piezoelectric element to replace the conventional solenoid valve.
종래의 솔레노이드 밸브는 전기 신호에 의해 플런저가 작동되어 개폐 역할을 하게 된다. 이러한 플런저는 보빈 사이에서 슬라이딩 운동을 하게 되는데, 보빈과 플런저 사이의 마찰에 의해서 플런저가 빨리 마모되어, 밸브의 개폐 신뢰성이 저하되었다.In the conventional solenoid valve, the plunger is operated by an electrical signal to open and close. Such a plunger is a sliding motion between the bobbin, the plunger is quickly worn by the friction between the bobbin and the plunger, the opening and closing reliability of the valve is lowered.
따라서, 본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 고안의 목적은 수축과 팽창이 가능한 압전 소자를 이용하여 미세한 개폐 작용으로서 사용할 수 있는 압전 소자를 이용한 밸브를 제공하는데 있다.Accordingly, an object of the present invention is to provide a valve using a piezoelectric element that can be used as a fine opening and closing action by using a piezoelectric element capable of contracting and expanding.
상기 본 고안의 목적을 달성하기 위한 압전 소자를 이용한 밸브의 일예로서, 전원에 연결된 압전 소자와, 상기 압전 소자의 일측에 장착된 로드와, 상기 로드의 단부에 장착된 밸브로 구성된다.As an example of a valve using a piezoelectric element for achieving the object of the present invention, it comprises a piezoelectric element connected to a power source, a rod mounted on one side of the piezoelectric element, and a valve mounted on the end of the rod.
이것에 의해, 종래의 플런저가 필요없게 되고, 정밀한 개폐 제어가 가능하게 된다.This eliminates the need for a conventional plunger and enables precise opening and closing control.

이하, 본 고안의 실시예를 도 1를 참조하여 상세히 설명하기로 한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1.
도 1을 참조하면, 본 고안에 따른 압전 소자를 이용한 밸브는 전원(Vcc)에 연결된 압전 소자(3)와, 상기 압전 소자(3)의 일측에 장착된 로드(5)와, 상기 로드(5)의 단부에 장착된 밸브(7)로 구성된다.Referring to FIG. 1, a valve using a piezoelectric element according to the present invention includes a piezoelectric element 3 connected to a power supply Vcc, a rod 5 mounted on one side of the piezoelectric element 3, and the rod 5. It consists of a valve (7) mounted at the end of the).
상기 밸브(7)는 흡입 챔버(9)와 배기 챔버(10) 사이를 연결하는 연결로(11)를 개폐하게 된다.The valve 7 opens and closes a connection path 11 connecting the suction chamber 9 and the exhaust chamber 10.
압전 소자(3)는 수정, 로셀염, 티틴산 바륨 등의 결정체에 전하를 가하면 팽창 또는 수축되는 것이다.The piezoelectric element 3 expands or contracts when an electric charge is applied to crystals such as quartz, rosell salt, barium titanate, and the like.
상기와 같은 구성에 의해 본 고안의 압전 소자를 이용한 밸브는 다음과 같이 작동한다.By the above configuration, the valve using the piezoelectric element of the present invention operates as follows.
압전 소자(3)에 (+) 전원이 인가되면, 압전 소자가 팽창하여 밸브를 흡입 챔버(9) 쪽으로 밀어서 연결로(11)가 개방된다.When positive power is applied to the piezoelectric element 3, the piezoelectric element expands and pushes the valve toward the suction chamber 9 to open the connection passage 11.
압전 소자(3)에 (-) 전원이 인가되면, 압전 소자가 수축하여 밸브를 배기챔버(10) 쪽으로 밀어서 연결로(11)가 폐쇄된다.When a negative power is applied to the piezoelectric element 3, the piezoelectric element contracts and the valve 11 is pushed toward the exhaust chamber 10 to close the connection path 11.
상술한 바와 같이 본 고안에 따른 압전 소자를 이용한 밸브는 압전 소자의 팽창이 극히 미세한 양이 되므로 극히 미세한 유공압 콘트롤에 효과적이다.As described above, the valve using the piezoelectric element according to the present invention is effective in controlling the microscopic pneumatic pressure since the expansion of the piezoelectric element becomes an extremely fine amount.
이상에서 설명한 것은 본 고안에 따른 압전 소자를 이용한 밸브를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 고안은 상기한 실시예에 한정되지 않고, 이하의 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is just one embodiment for implementing a valve using a piezoelectric element according to the present invention, the present invention is not limited to the above embodiment, the present invention claimed in the following utility model registration claims Various changes may be made by those skilled in the art without departing from the gist of the present invention.
