Abstract
Novel and improved forms of guide assemblies are provided for a swash plate type of air compressor, a first form of invention including a linear slider, which is movable up and down a support rod to maintain the rotational position of the swash plate relative to the cylinders of the compressor; a second form of guide assembly comprises a channel bracket in which a roller on the swash plate is movable as the swash plate undergoes reciprocal motion; and in a third form a series of complementary grooves and rollers are mounted at the interface between the motor housing and swash plate. In addition, a centrifugal force governor is employed in cooperation with a pressure sensor to maintain the desired pressure level within the manifold of the air compressor.
Claims17
In an air compressor including a motor for driving a shaft about a longitudinal axis, a swash plate connected to said shaft by an angled cam hub and a bearing to translate rotational motion of said shaft into reciprocal motion of a periphery of said swash plate, and a plurality of pneumatic cylinders arranged equidistantly about said longitudinal axis, each cylinder including a piston driven by a piston rod connected to said swash plate, wherein said improvement comprises:
- means for connecting a first end of said piston rod to said periphery of said swash plate, said connecting means having means for rotating said first end of said piston rod about a first axis substantially perpendicular to said longitudinal axis;
- means for rotating said first end of said piston rod about a second axis substantially perpendicular to both said first axis and said longitudinal axis;
- and
- said connecting means comprising a plurality of U-shaped slots formed equidistantly about said periphery of said swash plate for connecting said first ends of said piston rods, each said U-shaped slot comprising a pair of opposing arms extending outward from said periphery of said swash plate, and each pair of said opposing arms defining a pair of opposing openings therein, and wherein said means for rotating said first end of said piston rod about said first axis includes a pair of annular bearings positioned within said pair of said opposing openings;
- and an axle having opposing ends seated within said annular bearings of said opposing arms to allow said axle to rotate about said first axis, said axle connected to said first end of said piston rod.
In an air compressor including a motor for driving a shaft about a longitudinal axis, a swash plate connected to said shaft by an angled cam hub and a bearing to translate rotational motion of said shaft into reciprocal motion of a periphery of said swash plate, and a plurality of pneumatic cylinders arranged equidistantly about said longitudinal axis, each cylinder including a piston driven by a piston rod connected to said swash plate, wherein said improvement comprises:
- means for connecting a first end of said piston rod to said periphery of said swash plate, said connecting means having means for rotating said first end of said piston rod about a first axis substantially perpendicular to said longitudinal axis;
- means for rotating said first end of said piston rod about a second axis substantially perpendicular to both said first axis and said longitudinal axis;
- and
- guide means engageable with said swash plate for limiting rotation of said swash plate as said swash plate undergoes reciprocal motion.
In a compressor, a motor for driving a shaft about a longitudinal axis, a swash plate connected to said shaft to translate rotational motion of said shaft into reciprocal motion of said swash plate, the improvement comprising:
- guide means engageable with said swash plate for limiting rotation of said swash plate as said swash plate undergoes reciprocal motion, said guide means defined by a mounting portion having a first stabilizer plate mounted thereon, said swash plate having a second stabilizer plate mounted thereon in facing relation to said first stabilizer plate, and a plurality of complementary grooves and rollers mounted on said first and second stabilizer plates in aligned relation to one another and wherein said rollers are movable progressively into engagement with respective of said grooves in response to reciprocal motion of said swash plate.
