Abstract
Abstract A pump unit is provided with a housing enclosing a motor and a pump block flanged thereto. The housing closely follows the contours of the motor and the pump block and is provided with external projections for accommodating accessories for use with the pump unit. A handle is integrally formed at an upward projection of the housing, the upward projection serving as an enclosure for a capacitor connected to the motor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
225 words
A portable high-pressure pump unit including an electric motor and a pump block flanged to an end side of said motor and provided with an inlet duct, an outlet duct, at least one indicating device and manually operable setting means for controlling pump operation, comprising: a unitary housing formed of synthetic material, enclosing both said electric motor and said pump block, provided with openings for access to said inlet and outlet ducts and passing said manually operable setting means therethrough and giving sight to said indicating device, the shape of said unitary housing closely following the outer contours of the pump unit, with a groove-like recess formed in said housing, in a direction lateral to a longitudinal axis of said pump unit, in a region between said electric motor and said pump block at an upper side of said housing for receiving electric cable therein; a substantially horizontal forwardly extending handle integrally formed at an upwardly projecting part at a rear end portion of said unitary housing; laterally extending projections integral with said unitary housing for accommodating accessories necessary for an operation of said pump unit; a stable base support integrally formed with said unitary housing; and a semi-cylindrical box opening upward and formed to be integral with said housing at a lower rear end portion thereof for receiving and accommodating a hose roll therein.
