ABSTRACT:
An improved pressure button for an archery bow having a housing adapted to extend through an opening in a bow handle. The housing has a chamber disposed therein and the chamber extends to an opening in one end thereof. A plunger is slidably disposed within the chamber and the plunger has one end thereof extending through the opening and forming a small space between the one end of the plunger and the housing. An arrow contacting portion is disposed on one end of the plunger for contacting an arrow on an arrow rest, such arrow rest being attached to the bow handle. A spring is disposed within the plunger for biasing the plunger in a direction toward the arrow and a stop is provided for preventing the plunger from moving too far in such one direction. An opening is provided for permitting air to enter the chamber on the other end thereof and a pump is disposed within the chamber for causing air to be forced out through the space between the housing and the plunger when the plunger operates as a shock absorber and guiding mechanism for the arrow when it is shot. A filter is provided in the chamber to prevent dirt from entering the chamber.
