Abstract

A modular hose coupler for carrying air or other gas is described including in some embodiments a valve (1) designed to reduce air-hammer effects and improve aerodynamic flow. Some embodiments include self-lubrication. Some embodiments include a secure release ring (2) requiring twisting before release, reducing accidental release in debris-laden industrial environments. Other embodiments include sealing structures (01, 02, 03) designed for exclusion of dirt, robust performance and enhanced lifetime.

Claims

1. A valve for a hose coupler comprising a substantially cylindrical valve body having at least one row of holes circumferentially located around said valve body wherein said holes have locations on said valve body such that no two of said holes are diametrically aligned through the center axis of said valve body.

2. A valve as in claim 1 wherein said valve body has a tapered shape at one end of said valve body.

3. A valve as in claim 1 further comprising a substantially cylindrical valve base substantially coaxial with said valve body wherein said valve base further comprises a plurality of circumferential grooves suitable for the insertion of base sealing rings, thereby causing tight sealing between said valve base and the inner surface of the main body of said hose coupler.

4. A valve body as in claim 3 further comprising one or more tip sealing rings at the tip end of said valve body opposite said valve base.

8. A hose coupler comprising:

a) a valve as in claim 4; and

,

b) a substantially cylindrical main body surrounding said valve and substantially coaxial therewith, wherein said valve is capable of sliding substantially freely along the central axis of said main body and engaged by a valve spring; and

,

c) wherein at least one of said tip sealing rings forms a seal with the inner surface of said main body when said valve is in its closed position without sliding over said inner surface of said main body.

5. A hose coupler comprising:

a) a valve comprising a substantially cylindrical valve body having air holes therein, and a substantially cylindrical valve base substantially coaxial with said valve body; and

,

b) a substantially cylindrical main body surrounding said valve and substantially coaxial therewith, wherein said valve is capable of sliding substantially freely along the central axis of said main body and engaged by a valve spring; and

,

c) a substantially cylindrical release ring substantially coaxial with said main body and capable of sliding along the central axis of said main body to engage and disengage a valve coupler; and

,

d) wherein said valve body has at least one row of holes circumferentially located around said valve body wherein said holes have locations on said valve body such that no two of said holes are diametrically aligned through the center axis of said valve body.

6. A hose coupler comprising:

a) a valve comprising a substantially cylindrical valve body having air holes therein, and a substantially cylindrical valve base substantially coaxial with said valve body; and

,

b) a substantially cylindrical main body surrounding said valve and substantially coaxial therewith, wherein said valve is capable of sliding substantially freely along the central axis of said main body and engaged by a valve spring; and

,

c) a substantially cylindrical release ring substantially coaxial with said main body and capable of sliding along the central axis of said main body to engage and disengage a valve coupler; and

,

d) further comprising at least one locking bolt such that said release ring requires and angular movement about said central axis to enable disengagement of said valve coupler.

7. A hose coupler comprising:

a) a valve comprising a substantially cylindrical valve body having air holes therein, and a substantially cylindrical valve base substantially coaxial with said valve body; and

,

b) a substantially cylindrical main body surrounding said valve and substantially coaxial therewith, wherein said valve is capable of sliding substantially freely along the central axis of said main body and engaged by a valve spring; and

,

c) a substantially cylindrical release ring substantially coaxial with said main body and capable of sliding along the central axis of said main body to engage and disengage a valve coupler; and

,

d) further comprising at least one lubrication chamber circumferentially surrounding said valve body so as to dispense lubricant onto the outer surface of said valve body.
