Abstract
A pump mechanism for a horizontal compressor comprises: a partition plate disposed in a housing of the horizontal compressor to separate an oil compartment from a motor compartment provided with a motor; and a pump assembly including a first pump and a second pump located in the oil compartment. The first pump sucks oil from the motor compartment to the oil compartment. The second pump delivers the oil from the oil compartment to a lubrication channel inside a rotary shaft. The partition plate is made from a flat plate, and includes: a plate main body extending in a vertical direction; and a flange portion extending from the peripheral edge of the plate main body in an axial direction and secured to the housing. A horizontal compressor including the pump mechanism is also provided.
