no. 10 approach

[0189] The tenth embodiment has the following advantages.

[0190] The pressure regulator 5 is opened by an actuation force greater than the pressing force with which the actuating rod 11 is pressed by the membrane element 6 . This structure reduces the pressure bearing area of ​​the membrane member 6, making it possible to minimize and reduce the thickness of the valve device 1.

[0191] The membrane part 6 is sufficiently thin to withstand elastic deformations due to pressure changes in the pressure chamber 4 . Therefore, when the membrane element 6 presses against the actuating rod 11 , a relatively small reaction force acts on the membrane element 6 . Therefore, a small pressure-receiving area with a dome-like curved state can be installed.

[0192] The method of manufacturing the valve device 1 of the tenth embodiment, or more specifically, the method of manufacturing the valve device 1 of the tenth embodiment, or more specifically, by bending the thin film member 6 int...

Abstract

A valve device has a pressure chamber, which is connected to a liquid inlet and a liquid outlet and retains liquid, and a pressure regulator decreasing the pressure in the pressure chamber to a predetermined level. The pressure regulator has a pressure receiving member. When the pressure in the pressure chamber becomes lower than the predetermined level, the valve is close; the deformation part corresponding to the deformation of the pressure in the pressure chamber moves the valve from the close position to the opening position when the pressure in the pressure chamber is lower than the predetermined level; and when the valve in the close position, the valve and the excircle part of the inlet are tightly contacted to seal the sealing part of the inlet, wherein the holding part is nearer to the axial position than the sealing part to push the valve to the close position. When the pressure in the pressure chamber becomes greater than the predetermined level, the sealing part holds the valve in the close position.

Description

[0001] This application is a divisional application of a Chinese invention patent application with application number 200480004664.X (application date: December 24, 2004; title of invention: valve device, pressure regulator, carrier, liquid injection equipment). technical field [0002] The invention relates to a valve arrangement with a pressure regulator, a pressure regulator, a carrier, a liquid injection device and a method for producing the valve arrangement. Background technique [0003] A pressure regulator disclosed in Patent Publication 1 is considered to be a pressure regulator for reducing the pressure of a liquid to a constant level. [0004] As a conventional inkjet type printer, there is known a form in which an ink tank is supplied through an ink supply tube to a pressure damper installed in the ink tank (for example, see Patent Publication Document 2). Ink is then delivered from the pressure damper to the recording head for printing. If a considerable amount...
