Patent ID: 8573452

Claim:
A valve, comprising: a) a valve housing having an internal surface defining: i) a fluid delivery passage between an axially aligned valve inlet orifice and valve outlet orifice, said fluid delivery passage configured to flow an amount of fluid from an enclosed space of a fluid source, wherein said fluid delivery passage has a first part which terminates in a closed end; ii) a fluid delivery passage seat defining an aperture which communicates between opposed surfaces of a fluid delivery passage wall of said first part of said fluid delivery passage; iii) a second part of said fluid delivery passage disposed in substantially orthogonal adjacent relation to said fluid delivery passage wall of said first part, said second part having sufficient internal space to enclose and provide travel of a fluid delivery passage seal between a closed condition and an open condition of said valve, said second part of said fluid delivery passage providing orthogonal fluidic communication in said open condition of said fluid delivery passage seal between said first part of said fluid delivery passage and said valve inlet orifice; iv) a fluid compensation passage between a fluid compensation inlet orifice and a fluid compensation outlet orifice, said fluid compensation passage configured to flow an amount of compensation fluid to said enclosed space within said fluid source, said fluid compensation passage discrete from said fluid delivery passage; v) a fluid compensation passage seat coupled within said fluid compensation passage; and vi) a valve trigger guide having a longitudinal axis disposed in substantially orthogonal relation to a longitudinal axis of said first part of said fluid delivery passage and coaxial with said aperture; and b) a valve trigger telescopically engaged in said trigger guide, said valve trigger having a valve trigger stem which extends through said aperture of said fluid delivery passage seat which allows concurrent engagement of said fluid delivery passage seal with said fluid delivery passage seat and engagement of a fluid compensation passage seal with said fluid compensation passage seat to coincidentally establish a closed condition of said fluid delivery passage and a closed condition of said fluid compensation passage.
