Abstract
A method of reducing friction in an anti-chatter device. An applicator is provided which is insertable into a shaft biasing device cavity or orifice. The applicator is inserted into the cavity and a lubricant is injected through a hollow opening in the applicator. An anti-chatter device is then secured to the orifice and applies the lubricant to the short runner valve shaft via the orifice.
Claims6
A method for reducing friction in a short runner valve shaft biasing assembly comprising the steps of:
- (a) providing an anti-chatter device orifice adapted for receiving an anti-chatter device for engaging a short runner valve shaft, said orifice comprising a bore;
- (b) placing a lubricant in said orifice, wherein said lubricant is in fluid communication with said short runner valve;
- and
- (c) substantially fully inserting said anti-chatter device in said orifice.
A method for reducing friction in a short runner valve shaft biasing assembly, comprising the steps of:
- providing a short runner valve shaft member;
- providing an anti-chatter device orifice in physical cooperation with said short runner valve shaft member, said orifice comprising a bore;
- providing an anti-chatter device, said anti-chatter device operable to be substantially fully received within said orifice;
- and
- providing a source of lubricant in fluid communication which is injected within said orifice, wherein said anti-chatter device is thereafter inserted into said orifice, the lubricant providing reduced friction between said anti-chatter device and said short runner valve shaft member.
