摘要： A method and apparatus is provided that includes a hand pump having a handle locking mechanism, a counter bored nut, pivoting links, and unlocking valve assembly. The unloading valve assembly allows a pump operator to pump a larger volume of hydraulic fluid and/or to pump to higher pressures in first stage operation than a conventional pump which employs a direct-acting relief valve. The unloading valve also decreases the effort required to pump the handle during second stage operation. The handle locking mechanism allows the pump handle from moving during transporting and storing of the hand pump. The counter bored nut allows for more reservoir room than conventional hand pumps. The pivoting link allows for greater leverage of the handle during pumping.

摘要： A method and apparatus for ensuring a user to change a filter dryer of a refrigerant recovery unit having a refrigerant determining module that is configured to determine a condition of the refrigerant or an amount of refrigerant that has passed through the filter dryer, or a condition of the filter dryer, an alert device that notifies the user to change the filter dryer in response to the condition, a pressure module that regulates the pressure in the filter dryer, and a pressure-sensing device that is configured to detect a change of pressure in response to filter dryer maintenance. The refrigerant recovery unit is disabled from recovering refrigerant when the refrigerant determining module determines that the filter dryer needs to be replaced, and it is activated in response to the change of pressure detected by the pressure-sensing device.
