Definitions
- Airless spray pumps for the spraying of paints and other coatings.
- Airless spray pumps for the spraying of paints and other coatings via the airless method are well known and have traditionally been divided into two types, diaphragm pumps for the lower end of the market and reciprocating piston pumps for the higher end.
- US 5769321 discloses a yoke support for a reciprocating member in portable paint spraying equipment.
- a slot is provided in the housing perpendicular to an axis of reciprocation.
- An extension on the reciprocating member and removable support secured to the housing are also provided. The removable support allows installation and removal of the reciprocating member with clearance for the extension via the slot.
- US 4416588 discloses an air compressor for airless paint pumps in which an eccentric cam drives two pistons.
- An airless spray pump is provided with a single-acting piston pump which allows the use of a low-cost yoke drive. Motor and pump shaft are offset for most efficient force utilization.
- the main drive housing has a motor mounted to the rear thereof.
- a gear assembly uses gear teeth which are formed with a 5° helical angle and have a 25° pressure angle. This geometry combines the higher efficiency of straight cut gears with the noise reduction typified in a helical design.
- An eccentric is molded onto the front of the gear assembly and has located thereabout a bearing assembly which rides inside a yoke.
- the yoke moves vertically on guide rods which are retained in pockets of the drive housing.
- the yoke is molded of plastic as is the gear assembly leading to lower cost and easier manufacture.
- the pump rod is provided with a cap over the top end thereof which has bearing.
- Pump assembly is designed as a single acting pump, that is, the pump only pumps on the downward stroke and loads on the upward stroke. This allows the components of the drive train, including the yoke and gear, to be much lighter as the yoke ends up being more of a guidance device rather than a force-applying device.
- the motor and pinion are offset from the centerline of the pump assembly. This arrangement does not have any significant cantilevering as the pump rod, pinion, yoke, eccentric and cap are all located in the same plane.
- the location of the rod and the single acting pump with respect to the gear centerline reduces the thrust loads on the yoke.
- the location of the pinion on the gear partially offsets and reduces the pump forces on the gear shaft and bearings.
- the shaft packing assembly is comprised of a packing housing which screws into the pump housing and which contains a felt member which has been soaked with throat seal lubricant or other solvent or lubricant.
- a stack of v-packings are compressed in place by wave spring which is tightened by tightening the seal housing into the pump housing.
- the inlet check is provided with a check ball and a check seat which is pressed into a check housing and which is held in place by a retainer. These parts all press-fit into one another such that the complete assembly be merely screwed into main pump housing for replacement.
- outlet check assembly is formed of an outlet check housing which is screwed into a pump housing and similarly is provided with a check ball held in place by a retainer.
- the outlet passageway is angled relative to the axis of the pump shaft. This allows the outlet check assembly to operate essentially via gravity and yet requires only the drilling and provision of one passageway while maintaining an essentially vertical ball-seat relationship.
- the instant invention generally designated 10 is comprised of a main drive housing 12 having a motor 14 mounted to the rear thereof.
- a gear assembly 16 having a rear bearing 17 and gear teeth 22 is inserted into the bearing housing 20 of drive housing 12.

- Yoke 30 moves vertically on guide rods 32 which are retained in pockets 34 of drive housing 12.
- Yoke 30 is molded of plastic.
- Gear assembly 16 is cast in ZA-12 with an integral counterweight leading to lower cost and easier manufacture.
- Pump rod 36 is provided with a cap 38 over the top end thereof which has bearing upon it bearing 28.
- Pump assembly 40 is designed as a single acting pump that is the pump only pumps on the downward stroke and loads on the upward stroke.

Description
- Airless spray pumps for the spraying of paints and other coatings.
- Airless spray pumps for the spraying of paints and other coatings via the airless method are well known and have traditionally been divided into two types, diaphragm pumps for the lower end of the market and reciprocating piston pumps for the higher end.
- US 5769321 discloses a yoke support for a reciprocating member in portable paint spraying equipment. A slot is provided in the housing perpendicular to an axis of reciprocation. An extension on the reciprocating member and removable support secured to the housing are also provided. The removable support allows installation and removal of the reciprocating member with clearance for the extension via the slot.
- US 4416588 discloses an air compressor for airless paint pumps in which an eccentric cam drives two pistons.
- According to the present invention there is provided a spray pump powered by a rotary motor having a pinion thereon and comprising:
- a housing;
- a single-acting piston pump having a pump rod and connected to said housing;
- a drive gear assembly comprising a gear and an eccentric located on said gear;
- a bearing located about said eccentric;
- a yoke reciprocatingly located in said housing and about said bearing; and
- a cap located on said pump rod and in said yoke so as to contact said bearing.
- An airless spray pump is provided with a single-acting piston pump which allows the use of a low-cost yoke drive. Motor and pump shaft are offset for most efficient force utilization. The main drive housing has a motor mounted to the rear thereof. A gear assembly uses gear teeth which are formed with a 5° helical angle and have a 25° pressure angle. This geometry combines the higher efficiency of straight cut gears with the noise reduction typified in a helical design.
- An eccentric is molded onto the front of the gear assembly and has located thereabout a bearing assembly which rides inside a yoke. The yoke moves vertically on guide rods which are retained in pockets of the drive housing. The yoke is molded of plastic as is the gear assembly leading to lower cost and easier manufacture.
- The pump rod is provided with a cap over the top end thereof which has bearing. Pump assembly is designed as a single acting pump, that is, the pump only pumps on the downward stroke and loads on the upward stroke. This allows the components of the drive train, including the yoke and gear, to be much lighter as the yoke ends up being more of a guidance device rather than a force-applying device.
- The motor and pinion are offset from the centerline of the pump assembly. This arrangement does not have any significant cantilevering as the pump rod, pinion, yoke, eccentric and cap are all located in the same plane. The location of the rod and the single acting pump with respect to the gear centerline reduces the thrust loads on the yoke. The location of the pinion on the gear partially offsets and reduces the pump forces on the gear shaft and bearings. By locating the eccentric bearing directly on the end of the pump rod cap which is press-fit it eliminates the transfer of pumping force through an intermediate member such as the yoke which provides longer life, efficiency and allows the manufacture of a more inexpensive yoke assembly.
- The shaft packing assembly is comprised of a packing housing which screws into the pump housing and which contains a felt member which has been soaked with throat seal lubricant or other solvent or lubricant. A stack of v-packings are compressed in place by wave spring which is tightened by tightening the seal housing into the pump housing.
- The inlet check is provided with a check ball and a check seat which is pressed into a check housing and which is held in place by a retainer. These parts all press-fit into one another such that the complete assembly be merely screwed into main pump housing for replacement. Similarly, outlet check assembly is formed of an outlet check housing which is screwed into a pump housing and similarly is provided with a check ball held in place by a retainer. The outlet passageway is angled relative to the axis of the pump shaft. This allows the outlet check assembly to operate essentially via gravity and yet requires only the drilling and provision of one passageway while maintaining an essentially vertical ball-seat relationship.
- These and other objects and advantages will appear more fully from the following description made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views.

- FIG. 2 is a simple front plan view of the drive assembly and pump of the instant invention.
- FIG. 3 is a side plan view of the assembly shown in FIG. 1.
- FIG. 4 is a detailed exploded view of the circled area in FIG. 3.
- FIG. 5 is a cross-sectional view of the pump of the instant invention.
- FIG. 6 shows more details of the drive assembly of the instant invention.

- FIG. 8 is a cross-section of the outlet filter.
- FIG. 9 is an exploded view of the outlet filter.
- FIG. 10 is a perspective exploded view of the instant invention.
- The instant invention generally designated 10 is comprised of a
main drive housing 12 having amotor 14 mounted to the rear thereof. Agear assembly 16 having arear bearing 17 andgear teeth 22 is inserted into the bearinghousing 20 ofdrive housing 12.Gear teeth 22 ongear assembly 16 mate with the teeth onpinion 24 on the end ofmotor 14. Theteeth 22 and onpinion 24 are formed with a 5° helical angle and have a 25° pressure angle. This geometry combines the higher efficiency of straight cut gears with the noise reduction typified in a helical design. - An eccentric 25 is also molded onto the front of
gear assembly 16 and has located thereabout abearing assembly 28 which rides inside ayoke 30. Yoke 30 moves vertically onguide rods 32 which are retained inpockets 34 ofdrive housing 12. Yoke 30 is molded of plastic.Gear assembly 16 is cast in ZA-12 with an integral counterweight leading to lower cost and easier manufacture. -
Pump rod 36 is provided with acap 38 over the top end thereof which has bearing upon it bearing 28.Pump assembly 40 is designed as a single acting pump that is the pump only pumps on the downward stroke and loads on the upward stroke. In doing so this allows the components of the drive train, including the yoke and gear, to be much lighter as theyoke 30 ends up being more of a guidance device rather than a force-applying device. - As can be seen more particularly in FIG. 2, motor and
pinion 24 are offset from thecenterline 42 ofpump assembly 40 which also has offset therefrom bearing 20 in the opposite direction. Also, this arrangement does not have any significant cantilevering as the pump rod, pinion, yoke, eccentric and cap are all located in the same plane. The location of the rod and the single acting pump with respect to the gear centerline reduces the thrust loads on the yoke. The location of the pinion on the gear partially offsets and reduces the pump forces on the gear shaft and bearings. By locating the eccentric bearing directly on the end of the pump rod cap which is press-fit it eliminates the transfer of pumping force through an intermediate member such as the yoke which provides longer life, efficiency and allows the manufacture of a more inexpensive yoke assembly. - The
shaft packing assembly 44 shown in FIG. 4 is comprised of a packinghousing 46 which screws intopump housing 48 and which contains a feltmember 50 which has been soaked with throat seal lubricant or other solvent or lubricant. A stack of v-packings 52 are compressed in place bywave spring 54 which is tightened by tighteningseal housing 46 intopump housing 48. - Turning to FIG. 7,
inlet check 56 is provided with acheck ball 58, acheck seat 60 which is pressed intocheck housing 62 and which is held in place by retainer andintegral ball guide 64. These parts all press-fit into one another such that the complete assembly be merely screwed intomain pump housing 48 for replacement. Similarly, outlet check assembly is formed of anoutlet check housing 60 which is screwed intopump housing 48 and similarly is provided with acheck ball 62 held in place byball seat 65. As can also be seen in FIG. 7, theoutlet passageway 66 is angled relative to the axis ofpump shaft 36. This allows theoutlet check assembly 58 to operate essentially via gravity and yet requires only the drilling and provision of one passageway while maintaining an essentially vertical ball-seat relationship. - FIGs. 8 and 9 show the
outlet filter assembly 80 which is comprised of afilter element 82 contained inpassage 84 ofpump assembly 40 and which is retained by fitting 86. - Turning to FIG. 10,
inlet tube 70 is provided with a female threadedend 70a. Inletfilter screen assembly 72 has a male threadedend 72a for threaded engagement withend 70a.Ends screen assembly 72, attach a garden hose toinlet tube 70, turn on the water and flush out the assembly. - It is contemplated that various changes and modifications may be made to the airless spray pump without departing from the scope of the invention as defined by the following claims.
