摘要:
A trigger sprayer has a housing, a piston bore within the housing, and a piston reciprocally mounted within the piston bore. The housing further includes a flow passage through which liquid passes from a passage inlet to a passage outlet. An actuator is operable to reciprocate the piston within the piston bore between a vacuum stroke creating reduced pressure in the piston bore and a compression stroke creating increased pressure in the piston bore. A valve assembly within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve assembly further comprises a check valve and a priming valve. The sprayer has a closure for mounting the sprayer to a container. The valve seat for the check valve is in a component formed separately from and operatively connected to the housing.
