Abstract
A hydraulic tensioner can include a valve retainer and valve member within a housing including a cavity, passageway, and boss. The passageway provides fluid communication with the cavity through an end face of the cavity. The boss is disposed about the passageway and extends axially outward from the end face. The valve retainer can include a first plate. The first plate can be fixedly coupled to the housing. The valve member can include a second plate that can be axially between the first plate and the boss. The second plate can extend in a radial direction beyond an outermost edge of the boss. The second plate can move axially between a closed position wherein the second plate is in sealing contact with the boss and an open position wherein the second plate is axially spaced apart from the boss. The valve spring biases the second plate toward the closed position.
