Abstract:
1. A valve mechanism for controlling release of pressurized fluid, comprising: a housing; a fluid chamber defined within the housing, the fluid chamber having a fluid chamber inlet and having a plunger aperture and defining an interior volume; a plunger having a closed end and a plunger outlet end, the plunger having at least one plunger fluid passage extending partially along a length of the plunger from the plunger outlet end, the plunger having at least one plunger inlet defined in a longitudinal wall thereof in fluid communication with the at least one plunger fluid passage; the plunger being slidably received in the plunger aperture in sealing engagement therewith with the closed end within the interior volume of the fluid chamber so as to be movable between a fluid retention position in which the at least one plunger inlet is isolated from the interior volume of the fluid chamber and a fluid release position in which the at least one plunger inlet is in fluid communication with the interior volume of the fluid chamber; a plunger biasing member acting between the plunger and the housing to bias the plunger into the fluid retention position; a driver having a driving end and a driver outlet end and having at least one driver fluid passage extending therethrough between the driving end and the driver outlet end, the driver being slidably received within the housing for reciprocating, sliding movement of the driver within the housing for reciprocating, sliding movement of the driver within the housing; a plunger actuator having a plunger actuator inlet end and a plunger actuator outlet end, the plunger actuator having at least one plunger actuator fluid passage extending therethrough between the plunger actuator inlet end and the plunger actuator outlet end, the plunger actuator received within the housing between the plunger and the driver; and a guide mechanism for: wherein at least when the plunger is in the fluid release position, the at least one plunger fluid passage is in fluid communication with the at least one plunger actuator fluid passage and the at least one plunger actuator fluid passage is in fluid communication with the at least one driver fluid passage.
