  • Reciprocating pump with internal venting
    Patent number: 11859762
    Abstract: A lubricant pump includes a housing mountable to the upper end of a lubricant container and having a vertical central bore, an outlet passage extending between the central bore and an outlet port fluidly connectable with the lubricant distributor and a vent chamber having an inlet and an outlet. A vent inlet passage extends between the central bore and the vent chamber inlet and a vent outlet passage extends between the vent chamber outlet and a vent outlet port fluidly connectable with a container cavity. A movable valve element is disposed within the vent chamber and displaceable along an axis between a position in which the valve element obstructs the chamber inlet and/or the chamber outlet and a second position in which the chamber inlet is fluidly connected with the chamber outlet to provide an internal flow path from the central bore to the vent outlet port.
