Structure for motor-compressor units used with refrigerant fluids

Claim 2

A structure for motor-compressor units used with refrigerant fluids comprising: a casing; a bulkhead, spanning the interior of the casing transversely and, with said casing, forming a chamber on one side thereof, and a motor housing on the other side thereof, wherein both said chamber and said motor housing reside within the casing, said bulkhead forming a sealed barrier between said chamber and said motor housing; a compressor, occupying the chamber and having a shaft, the shaft of which passes thru the bulkhead in a fluid-tight fit; a motor, mounted internally of the housing; at least one gallery, incorporated into the casing, which is disposed peripherally in relation to the motor housing and communicates with the chamber occupied by the compressor, said gallery being sealed with respect to said motor housing; and removable coupling means serving to connect the compressor shaft with the motor and enable operation of the unit.

Claim 3

A structure for motor-compressor units used with refrigerant fluids comprising: a casing; a bulkhead, spanning the interior of the casing transversely and, with said casing, forming a chamber on one side thereof, and a motor housing on the other side thereof, wherein both said chamber and said motor housing are within the casing said bulkhead forming a sealed barrier between said chamber and said motor housing; a compressor, occupying the chamber and having a shaft, the shaft of which passes thru the bulkhead in a fluid-tight fit; a motor, mounted internally of the housing; a compartment incorporated into said casing adjacent to the motor housing; a heat exchanger, accommodated in said compartment and communicating therewith in such a way as to enable the passage of fluid; and removable coupling means serving to connect the compressor shaft with the motor and enable operation of the unit.

Claim 4

A structure for motor-compressor units used with refrigerant fluids comprising: a casing; a bulkhead, spanning the interior of the casing transversely and, with said casing, forming a chamber on one side thereof, and a motor housing on the other side thereof, wherein both said chamber and said motor housing are within the casing said bulkhead forming a sealed barrier between said chamber and said motor housing; a compressor, occupying the chamber and having a shaft, the shaft of which passes thru the bulkhead in a fluid-tight fit; a motor, mounted internally of the housing; a compartment incorporated into said casing adjacent to the motor housing; a heat exchanger, accommodated in said compartment and communicating therewith in such a way as to enable the passage of fluid; and removable coupling means serving to connect the compressor shaft with the motor and enable operation of the unit.

Claim 5

Motor-compressor unit structure as in claim 2, wherein the motor is coupled directly to the shaft of the compressor, ensheathing it in a fluid-tight fit.

Claim 6

Motor-compressor unit structure as in claim 2, wherein the motor housing is provided with a removable base that fastens to the casing at the end of the housing opposite from the bulkhead.

Claim 7

A structure for motor-compressor units used with refrigerant fluids, comprising: a casing; a bulkhead, spanning the interior of the casing transversely and, with said casing, forming a chamber on one side thereof, and a motor housing on the other side thereof, wherein both said chamber and said motor housing are within the casing said bulkhead forming a sealed barrier between said chamber and said motor housing; a compressor, occupying the chamber and having a shaft, the shaft of which passes through the bulkhead in a fluid-tight fit; a motor, mounted internally of the housing; a compartment incorporated into said casing adjacent to the motor housing; at least one gallery, incorporated into the casing which is disposed peripherally in relation to the motor housing and communicates with the chamber occupied by the compressor, said gallery being sealed with respect to said motor housing; a heat exchanger, accommodated in a compartment that is incorporated into the casing adjacent to the motor housing and communicates therewith in such a way as to enable the passage of fluid; and removable coupling means serving to connect the compressor shaft with the motor and enable operation of the unit.

Claim 8

A structure for motor-compressor units used with refrigerant fluids, comprising: a casing; a bulkhead, spanning the interior of the casing transversely and, with said casing, forming a chamber on one side thereof, and a motor housing on the other side thereof, wherein both said chamber and said motor housing are within the casing said bulkhead forming a sealed barrier between said chamber and said motor housing; a compressor, occupying the chamber and having a shaft, the shaft of which passes through the bulkhead in a fluid-tight fit; a motor, mounted internally of the housing; a compartment incorporated into said casing adjacent to the motor housing; at least one gallery, incorporated into the casing which is disposed peripherally in relation to the motor housing and communicates with the chamber occupied by the compressor, said gallery being sealed with respect to said motor housing; a heat exchanger, accommodated in a compartment that is incorporated into the casing adjacent to the motor housing and communicates therewith in such a way as to enable the passage of fluid; and removable coupling means serving to connect the compressor shaft with the motor and enable operation of the unit.

Claim 9

Motor-compressor unit structure as in claim 5, wherein the motor is coupled directly to the shaft of the compressor, ensheathing it is a fluid-tight fit.

Claim 10

Motor-compressor unit structure as in claim 5, wherein the gallery is embodied as peripheral seats created internally of the housing between the casing and the outer wall of the hollow mounting that contains the motor.

Claim 11

Motor-compressor unit structure as in claim 5, wherein the motor housing is provided with a removable base that fastens to the casing at the end of the housing opposite from the bulkhead.

Claim 12
