Abstract
A turbulence reducer integrated in a vacuum breaker of a hydrant to reduce leakage during use of the hydrant by reducing turbulence acting on the vacuum breaker poppet.
Claims19
In combination with a water fixture, a flow turbulence reducer assembly comprising:
- a vacuum breaker valve body;
- a vacuum breaker poppet valve received in said vacuum breaker valve body;
- and
- a turbulence reducer having an annular circumference;
- said vacuum breaker valve body and said vacuum breaker poppet valve mounted in an aperture in the water fixture;
- said turbulence reducer mounted across the aperture between the aperture and said vacuum breaker poppet valve;
- said vacuum poppet valve contacting said annular circumference of said turbulence reducer;
- whereas said turbulence reducer diminishes the turbulence of water entering the water fixture aperture thereby reducing the leakage of water from the vacuum breaker assembly.

In combination with a water fixture, a vacuum breaker assembly comprising:
- a vacuum breaker valve body having a seat;
- a vacuum breaker poppet valve received in said vacuum breaker valve body, and
- a turbulence reducer having an annular circumference;
- said vacuum breaker valve body and said vacuum breaker poppet valve mounted in an aperture in the water fixture;
- said turbulence reducer mounted across the aperture between the aperture and said vacuum breaker poppet valve;
- said vacuum poppet valve contacting said annular circumference of said turbulence reducer;
- whereas said turbulence reducer diminishes the turbulence of water passing through the water fixture and entering the vacuum breaker assembly through the aperture;
- whereas said vacuum breaker poppet valve is sealed against said seat by a constant pressure of the water passing through the aperture;
- whereby reducing the leakage of water from the vacuum breaker assembly.

In combination with a water fixture, a vacuum breaker assembly comprising:
- a vacuum breaker valve body having a seat;
- a vacuum breaker poppet valve received in said vacuum breaker valve body;
- a washer for sealing said vacuum breaker poppet valve against said seat;
- a turbulence reducer having a perforated surface and an annular circumference;
- and
- a cap;
- said vacuum breaker valve body, washer and said vacuum breaker poppet valve mounted in an aperture in the water fixture;
- said turbulence reducer mounted across the aperture between the aperture and said vacuum breaker poppet valve;
- said vacuum poppet valve contacting said annular circumference of said turbulence reducer;
- said cap secured to and covering said vacuum breaker valve body within the aperture;
- whereas said turbulence reducer diminishes the turbulence of water passing through the water fixture and entering the vacuum breaker assembly through the aperture;
- whereas said washer and said vacuum breaker poppet valve is sealed against said seat by a constant pressure of the water passing through the aperture;
- whereby reducing the leakage of water from the vacuum breaker assembly.
