Problems solved by technology

It is foreseeable that due to factors such as the manufacturing error, material composition, starting point, aging speed, and size change caused by the lubrication effect of the O-ring, it will affect the operation standard of the valve equipment, especially the control related to the operation. The pressure ratio at which the air valve opens, and the operation-related influence of dirt or dust substances from the outside that can enter the exhaust valve

Embodiment Construction

[0028] Referring now to the present invention in detail, the valve arrangement used in any apparatus requiring control of pressure is the same arrangement. A person skilled in the art will be able to use the valve arrangement in any such device, such as a pressurized circuit maintaining the pressure of the tires of a controlled vehicle.

[0029] The valve device according to the invention comprises a valve body 13 enclosing an inlet loop or inlet passage 15A extending longitudinally between two air ports, namely the respective ports of the valve body 13. An air inlet port 17A and an air outlet port 17C are provided at longitudinally opposite ends 19 . The air inlet port 17A is used for the inflow of inflation air and is therefore coupled to the pressurization device ductwork (not shown) and receives the pressurized air from the ductwork as well as the valve for controlling the valve device 11. stress signal. An air outlet port 17C is coupled to the tire inner tube (not shown...

Abstract

A pressure-controlled three-way valve device for inflating, keeping inflated and deflating tires, the device having a plunger axially traversed by an inlet passage normally closed by a spring-urged inlet valve. The plunger's outer sidewall has a recess in which an O-ring extends to abut against the steps of the recess to limit the plunger stroke and keep an outlet circuit closed to a venting port formed in the sidewall of the body of the device. The plunger moving between a position to open air supply to the tire, a position to keep an outlet circuit to a tire closed and a position to open a venting port to deflate the tire. The plunger being mounted into the valve body by a diaphragm sealing an outer wall of the plunger against the valve body and permitting the moving of the plunger with minimal friction between the plunger and the valve body.

Description

technical field [0001] The present invention relates to a valve arrangement for installation in a pressurized gas or air piping system, which can be controlled by relative atmospheric pressure applied to a port of the valve arrangement or by a gap between two ports, channels or loops. differential pressure to control. According to the present invention, the state of the valve device is remotely controlled by changing the air pressure applied to one end of the piping system and through the air pressure in the piping system connected to the port, channel or loop without auxiliary control lines. In particular, the present invention relates to a three-state valve apparatus with reduced friction between valve components and more precise and efficient operation, which valve apparatus is adapted to Effectively assume a closed position, an open position between a pair of ports, or an open position between another pair of ports. [0002] The valve arrangement provided by the present ...
