A cover for use with a motor and handle extending from the motor comprising, a soft, resilient, fairly rigid, thermoplastic elastomeric material of one-piece construction. The cover has a first body portion having a sidewall and a dome extending from the sidewall defining a cavity to receive the motor, with the dome being spaced from the motor to define a chamber between said dome and motor which serves as a muffler to reduce noise. The cover has a hollow second body portion extending from the first body portion and having a bore to receive the handle.

A valve assembly for use with a fluid-driven tool having an elongated conduit with a bore communicating with the source of fluid, and an elongated valve member received in the bore. The valve assembly has a ball received in a chamber defining a valve seat, with the chamber communicating with the source in order to drive the ball against the seat. The valve assembly has a valve pin extending through the conduit in order to actuate and move the ball away from the valve seat to permit passage of the fluid through the valve member past the seat, and a paddle for actuating the valve pin in order to open the valve.

An improved, fluid driven rotary motor of the vane type includes a housing having a rotor cover disposed between a pair of end plates, a rotor rotatably mounted in the housing and a drive shaft torsionally affixed to the rotor. In the improved rotary motor of the invention, the rotor is slidable on the drive shaft so that the axial position of the rotor is permitted to "float" with respect to the housing. The degree of axial displacement, or degree of "float", is limited by a compression spring means and an abutting ring which cooperate with a pair of bearings in the end plates so that contact between the rotor and housing is avoided. Furthermore, the compression spring means is operative to force the rotor to return to a predetermined normal operating position upon axial displacement of the rotor.

The ratchet tool comprises an elongated housing and a drive body carried by the housing and being rotated by a ratchet ring the toothed opening of which is in engagement with a pawl carried by the drive body. A pocket in the ring has semi-cylindrical side surfaces which engage mating semi-cylindrical surfaces of the pocket. The front of the pocket is flat, thereby increasing the thickness of the region between the pocket and the toothed opening. With increased thickness, the stress in such region is reduced and the ring is less likely to crack during use.

Aspects are provided for positive displacement pumps and methods and systems for controlling such pumps to provide alerts based on user configurable tubing usage limits. A pump may include a user interface, a memory storing processor executable instructions, and a processor coupled with the user interface and the memory and configured to execute the instructions to receive a configuration of a tubing usage limit via the user interface. The processor may be configured to operate the pump according to a program. The processor may be configured to measure a tubing usage during pump operation. The processor may be configured to generate an alert when the tubing usage reaches the tubing usage limit.
