A high-pressure pump has a housing whose cylindrical chamber is subdivided by a piston into a fixed-volume compartment and a variable-volume compartment. An orbital crank is connected via a connecting rod to this piston to reciprocate it in the housing and thereby cyclically increase and decrease the volume of the variable-volume compartment. This variable-volume compartment is connected via a downstream conduit and a checkvalve to a supply of liquid lubricant, and to an upstream conduit and an upstream checkvalve both to the fixed-volume compartment and to the joints or bearings at the end of the connecting rod. |
