Trigger activated vented valve system

A method of providing a valve, comprising the steps of:

• a) establishing 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 coupled to said valve, wherein said fluid delivery passage has a first part which terminates in a closed end;
• b) locating 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;
• c) disposing a second part of said fluid delivery passage in substantially orthogonal adjacent relation to said fluid delivery passage wall, said second part having sufficient internal space to enclose and provide travel of a fluid delivery passage seal between a closed condition an open condition, 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;
• d) establishing a fluid compensation passage between a fluid compensation inlet orifice and fluid compensation outlet orifice, said fluid compensation passage configured to flow an amount of compensation fluid to within said enclosed space of said fluid source, said fluid compensation passage discrete from said fluid delivery passage;
• e) locating a fluid compensation passage seat within said fluid compensation passage;
• f) providing a valve trigger guide configured to telescopically receive a valve trigger, said 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;
• g) telescopically engaging said valve trigger in said valve trigger guide, said valve trigger having a valve trigger stem which extends through said aperture of said fluid delivery passage seat to locate said fluid delivery passage seal to releasably engage said fluid delivery passage seat upon telescopic travel of said valve trigger in said trigger guide;
• h) locating a fluid compensation passage seal in said fluid compensation passage which upon telescopic travel of said valve trigger in said trigger guide releasably seals with said fluid compensation passage seat;
• and
• i) configuring said valve trigger to generate concurrent releasable seal of said fluid delivery passage seal with said fluid delivery seat and said fluid compensation passage seal with said fluid compensation passage seat.

A method of using a valve, comprising the steps of

• a) generating travel of a valve trigger within a valve trigger guide of a valve housing having an internal surface defining:
• i) a fluid delivery passage between an axially aligned valve inlet orifice and valve outlet orifice configured to flow an amount of fluid from said enclosed space of said fluid source to said valve outlet, wherein said fluid delivery passage has a first part which terminates in a closed end and having 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;
• ii) a second part of said fluid delivery passage disposed in substantially orthogonal adjacent relation to said fluid delivery passage wall, 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 the fluid delivery passage and said valve inlet orifice;
• iii) 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 in contact with said internal surface of said fluid source, said fluid compensation passage discrete from said fluid delivery passage;
• and
• iv) a fluid compensation passage seat coupled within said fluid compensation passage, said 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 wherein said valve trigger has a valve trigger stem which extends through said aperture of said fluid delivery passage seat which allows 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 concurrently establish a closed condition of said fluid delivery passage and a closed condition of said fluid compensation passage;
• b) disengaging a said fluid delivery passage seal from a fluid delivery passage seat located in a fluid delivery path of said valve concurrent with disengaging a said fluid compensation passage seal from a fluid compensation passage seat located in a fluid compensation passage of said valve in response to travel of said valve trigger in said valve trigger guide;
• c) generating a flow of said amount of fluid contained in said enclosed space of said fluid source in a fluid delivery flow path of said fluid delivery passage between a valve inlet orifice and a valve outlet orifice concurrent with generating a flow of an amount of compensation fluid in said fluid compensation flow path of said fluid compensation passage between a fluid compensation passage inlet orifice located external to said enclosed space and a fluid compensation passage outlet orifice internal to said enclosed space;
• d) compensating reduction in said amount of fluid contained in said enclosed space with an amount of compensation fluid in said enclosed space to reduce change of pressure within said enclosed space during flow of said amount of fluid through said fluid delivery passage.
