  • Patent number: 7032713
    Abstract: A battery operated grease gun has a motor that drives a planetary gear assembly that is coupled to a pump assembly that drives a plunger reciprocally in an grease passage to discharge grease through a discharge spout. The pressure in the grease exerts a reaction force on the plunger that will change torque of the motor. The change of the torque of the motor will simultaneously effect voltage applied to the motor. When the voltage in the motor changes, an electronic pressure regulator measures the voltage in the motor to determine the pressure in the grease in the grease passage and stops the motor as the pressure in the grease reaches preset given valves in the pressure regulating device.

  • Patent number: 7021172
    Abstract: A hydraulically operated throttle system that has the hydraulic system components installed entirely within the throttle grip on the handlebar. A regular throttle cable is run through the frame/handlebar where it connects to the hydraulic system. A three-piston system is used to provide the control. One piston is connected to a disk cam. As the disk is turned (by turning the twist grip), the cam forces the first piston to move, which forces hydraulic fluid from a first cylinder into a secondary cylinder. This secondary cylinder contains a second piston, which is moved by the fluid from the first cylinder. As this second piston moves, hydraulic fluid moves third piston within a third cylinder. The third piston is attached to the throttle cable. As this piston moves within the third cylinder, it pulls or pushes the throttle cable, thereby opening or closing the throttle on the engine.

  • Patent number: 7021426
    Abstract: A cable is installed in a protective duct or guide tube by means of blowing (and, optionally, synergetic pushing) and lubricating the cable during installation. Lubricating the cable is done after the cable exits from the cable blowing equipment and hence takes place in a pressurized airflow passage. A hollow chamber filled with foam-plugs saturated with lubricant forms the cable lubricator. Lubricant is wiped onto the cable as it moves through the pressurized lubrication compartment. A portion of the airflow used for propelling the cable during blowing installation is bypassed around the lubricator and injected into the duct trajectory downstream of the lubricator.

  • Patent number: 7013747
    Abstract: An internal recirculating ball screw and nut system that is easier to manufacture and more reliant by virtue of a particular configuration of the grooves on the interior of the nut or the follower. Crossback portions of select nut grooves are arranged in a manner that allows the bearing balls to recirculate by slipping over the top of adjacent thread lands of the screw, advancing and recirculating within a single 360 degree rotation within said nut. Said recirculation is accomplished solely through the design of the path of a unitary nut, without use of any ancillary devices.

  • Patent number: 7010996
    Abstract: A cam locking assembly for an adjustable steering column. The assembly includes a tie bolt that is secured relative to the steering column. A lever member is positioned for rotation about the tie bolt. A caming unit is positioned about the tie bolt adjacent the lever member. The caming unit has a roller assembly positioned between a pair of opposed cam plates. One of the cam plates is associated with the lever member and rotates therewith and the other plate is fixed relative to such rotation. Each cam plate has a plurality of ramped recesses on its internal surface such that rotation of the one plate causes the rollers to ride up the ramps such that the plates are pushed apart. The pushed apart ramps cause clamping upon the steering column to lock its position.

An axle driving apparatus comprising a tubular reservoir tank erected on the upper surface of the upper wall surface of the housing for accommodating an HST, wherein, since the reservoir tank is thinly elongated and is freely bendable, it can be disposed in a limited space. The housing is divided into a first room and a second room with which the reservoir tank communicates. Further, a first magnet is disposed at a position where the first and second rooms are connected, and a second magnet is disposed in the proximity of an oil filter connected to a closed circuit of the HST so that impurities can be removed.

  • Patent number: 7007773
    Abstract: A lubrication device lubricates traveling lubrication sites, such as on a belt (1), in particular, on a roller or chain belt (1). The lubrication device includes a lubricating apparatus (2) having a catch (C) that is capable of assuming a resting position and a catching position relative to the belt (1). In the catching position, a lubricating head (D) of the lubricating apparatus (2) is moved to a lubrication site by relative lateral motion between the belt (1) and the lubricating apparatus (2) in order to supply lubricant to the lubricating site. At the end of the run path, the lubricating head (D) as well as the catch (C) moves relative to the belt (1) to return back to the resting position. Also, before or simultaneously while the catch (C) is brought into engagement with the belt (1), the lubricating apparatus (2) can be extended in a longitudinal direction of the lubrication site motion at a boosting speed, which is greater than zero and less than the speed of the belt (1).
