Abstract
A universal compressor device includes a cylinder formed in a shell, a shaft rotatably and slidably received in the cylinder, three or more pistons slidably received in the cylinder to alternatively actuate the shaft to move axially relative to the cylinder, and two valve plates disposed on ends of the cylinder to control fluid flowing passage. One cover and one cap are selectively secured to the ends of the cylinder, to enclose and retain the elements within the cylinder of the shell, and for attaching to one vehicle. One or more other covers and caps may further be selectively secured to the cylinder of the shell, for attaching the universal compressor device to the other vehicles.
Description
- The present invention is related to U.S. patent application Ser. No. 10/722,659, filed 24 Nov. 2003, pending.
- 1. Field of the Invention
- The present invention relates to a universal compressor assembly, and more particularly to a universal compressor assembly for assembling onto various vehicles or the like.
- 2. Description of the Prior Art
- Typical compressors comprise three or more pistons slidably received in one or more cylinders, in order to form a reciprocating piston type compressor of axial design.
- The typical compressors are normally disposed in the engine compartment of vehicles, and coupled to the refrigerant systems for pumping coolant or other agents through the refrigerant piping systems.
- Normally, various kinds of typical compressors are designed for attaching or coupling to the engines of different vehicles. For example, the compressors designed for such as GM® or FORD® vehicles may only be used in GM® or FORD® vehicles only, and may not be attached to the other vehicles.
- Similarly, the compressors designed for VOLKSWAGEN® or NISSAN® or TOYOTA® vehicles, for example, may only be used in VOLKSWAGEN® or NISSAN® or TOYOTA® vehicles only, and may not be attached to the other vehicles; i.e., the compressors are all designed for being secured or attached onto one particularly designed refrigerant system of one particular or selected vehicle only, and no parts or elements of the compressors may be used commonly.
- For vehicle repairing shops or companies, they have to order and store various kinds of compressors in stock for different vehicles. In addition, the vehicle repairing shops or companies have to prepare or rent a large space or building to store many compressors for different vehicles.
- For some of the vehicle repairing companies who have no spare spaces or buildings to store the compressors, the vehicle repairing companies thus have to order the required compressors from particular companies when required. Some times, it may take a long time to wait for a compressor.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional universal compressor assemblies.
- The primary objective of the present invention is to provide a universal compressor assembly including one or more caps or covers for selectively attaching to a universal compressor body, and for allowing the universal compressor assembly to be easily and selectively attached to different vehicles.
- The other objective of the present invention is to provide a universal compressor assembly including fewer parts or elements required to be stored, for reducing the required storing spaces or buildings for the compressors for different vehicles.
- In accordance with one aspect of the invention, there is provided a universal compressor assembly comprising a shell including two ends and a cylinder provided therein, a shaft rotatably and slidably received in the cylinder and including a cam member disposed thereon, at least three pistons slidably received in the cylinder and engageable with the cam member, to alternatively actuate the shaft to move axially relative to the cylinder, two valve plates disposed on ends of the cylinder to control fluid flowing passage, a first cover and a first cap selectively secured to the ends of the shell, to enclose and retain the cylinder and the shaft and the pistons and the valve plates within the shell, and for attaching to one vehicle. One or more second covers and one or more second cap may further be provided to be selectively secured to the ends of the shell, to enclose and retain the cylinder and the shaft and the pistons and the valve plates within the shell, and for attaching to the other vehicles when the first cover and the first cap are disengaged from the ends of the shell.
- The shell and the cylinder and the shaft and the pistons and the valve plates may thus be commonly used for all of the compressors. Only the covers and caps are required to be changed or replaced with the other ones, for attaching onto different vehicles.
- Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
-
FIG. 1 is a partial exploded view of a universal compressor assembly in accordance with the present invention; -
FIG. 2 is another partial exploded view of the universal compressor assembly; -
FIGS. 3, 4 , 5 are perspective views illustrating three different arrangements of the universal compressor assembly; and -
FIGS. 6, 7 , 8 are partial exploded views of the universal compressor assemblies as shown inFIGS. 3-5 respectively. - Referring to the drawings, and initially to
FIGS. 1 and 2 , a universal compressor assembly in accordance with the present invention comprises ashell 10 including acylinder 11 formed or provided therein and formed integral with each other, ashaft 12 rotatably and slidably received in thecylinder 11 of theshell 10 and including acam member 13 disposed thereon, and three ormore pistons 14 slidably received in thecylinder 11 of theshell 10 and engageable with thecam member 13, to alternatively actuate or force theshaft 12 to move axially along or relative to thecylinder 11 of theshell 10. - The universal compressor assembly further comprises a
first cover 20 and afirst cap 30 selectively secured to the ends ofcylinder 11 of the shell 10 (FIGS. 3, 6 ), to enclose thecylinder 11 and to retain theshaft 12 and thepistons 14 within thecylinder 11 of theshell 10. The universal compressor assembly further comprises twovalve plates cylinder 11, and to be received in thefirst cover 20 and thefirst cap 30 respectively for controlling the flowing passage or directions of the fluid or coolant agent to be pumped by the universal compressor assembly. Thefirst cover 20 and thefirst cap 30 are designed or shaped for attaching or securing to one refrigerant system of one of the vehicles, for example. - The universal compressor assembly further comprises one or more
second covers second caps FIGS. 4, 7 ; and 5, 8), for attaching or securing to the refrigerant systems of the other vehicles. Aclutch device 40 is normally provided and attached to theshaft 12 for clutching purposes. - As shown in
FIGS. 3-5 and 6-8, thecylinder 11 of theshell 10 and theshaft 12 and thepistons 14 and thevalve plates first cover 20 and thefirst cap 30, or thesecond covers second caps - The users, particularly the vehicle repairing companies or shops, may only be required to prepare and store one set of the
cylinder 11 of theshell 10 and theshaft 12 and thepistons 14 and thevalve plates - It is to be noted that all of the universal compressors may use the same or the
identical cylinder 11 andshaft 12 andpistons 14 andvalve plates cylinder 11 and theshaft 12 and thepistons 14 and thevalve plates - The universal compressors benefit the vehicle repairing companies much, because they are not required to order and store various kinds of compressors in stock for different vehicles, and they may prepare or order fewer compressor parts or elements for different vehicles, and they need not to rent a large space or building to store the compressors parts or elements.
- Accordingly, the universal compressor assembly in accordance with the present invention includes one or more caps or covers for selectively attaching to a universal compressor body, and for allowing the universal compressor assembly to be easily and selectively attached to different vehicles, and includes fewer parts or elements required to be stored, for reducing the required storing spaces or buildings for the compressors for different vehicles.
- Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
