A flow guide configured for insertion in a cavity defined between an outer housing and a nested inner motor housing of a fluid driven tool. The flow guide defines a longitudinal axis and includes at least two longitudinal portions disposed parallel to the longitudinal axis and defining a longitudinal channel therebetween, and a rib being substantially circumferential and connecting the longitudinal portions at points defining a plane substantially transverse to the longitudinal axis. The rib defines a recess that permits fluid communication in the longitudinal channel across the rib.

A fluid driven tool has an outer housing and an inner motor housing nested in the outer housing and defining a cavity therebetween that has a first end with a first exhaust passageway and a second end with a second exhaust passageway. The inner motor housing has a motor chamber with an inlet port for a fluid driven motor and fluid inlet, and an inlet manifold disposed in the cavity. The inlet manifold has a recessed portion with a surrounding seal that engages the inner motor housing and connects the fluid inlet to the at least one inlet port of the inner motor housing. An inner surface of the outer housing and an outer surface of the inner motor housing have portions that mate upon nesting the inner motor housing in the outer housing and provide reinforced areas for clamping regions of the outer housing located over the reinforced areas.

A locking assembly for the spindle of a tool includes a locking member, a biasing member interconnected with the locking member, and a collar surrounding a portion of the spindle. The spindle includes a spindle slot that receives the locking member to lock the spindle with respect to the tool housing. The collar may be rotated into an unlocked position in which the biasing member holds the locking member out of engagement with the spindle slot. The collar may also be rotated into a locked position in which a cam surface in the collar acts on the biasing member to apply a biasing force on the locking member toward engagement with the spindle slot. The biasing member may deflect to accommodate rotation of the collar into the locked position with the spindle slot not aligned with the locking member.

Hand-held power tools with an external composite sleeve having a forward portion and a rearward portion and defining an axially extending cavity. The power tools also include an internal metal housing having a substantially cylindrical body with a plurality of circumferentially spaced apart, longitudinally-extending front posts that project radially outward from the cylindrical body. The metal housing resides in the composite sleeve. The front posts can be closely spaced to or abut an inner surface of the forward end (e.g., front cap) of the sleeve. In a front exhaust configuration, the front posts and sleeve cooperate to define a plurality of circumferentially spaced apart gap spaces, a respective gap space bounded by adjacent posts, an outer surface of the cylindrical body and the inner surface of the sleeve.

In at least one illustrative embodiment, a grinding tool may comprise a housing including a mount, a shaft extending from the mount along a drive axis, where the shaft is configured to support a grinding wheel for rotation about the drive axis, and a guard coupled to the mount. The guard may comprise a central ring extending around the mount, a shroud extending radially outward from the central ring along a first portion of a circumference of the central ring, and a standoff coupled to a second portion of the circumference of the central ring. The standoff may extend from the central ring along a direction substantially parallel to the drive axis such that the standoff limits rotation of the guard about a tipping axis that is substantially perpendicular to the drive axis.

An improved torque control and fluid shut-off mechanism for a fluid operated tool includes a driving clutch member and a driven bit holder connected by ball bearings retained by the clutch member which engages in pockets in the bit holder. The pockets include a specific ramp construction which insures that the threshold torque level of the tool in the forward direction is less than the threshold level in the reverse direction.

An improved torque control mechanism for a rotary vane, air motor tool includes acceleration and speed responsive slidable elements positioned in grooves that lie in a plane transverse to the spin axis of the motor and which form an angle with the radii extending from the spin axis. The elements cooperate with a cam plate which operates a fluid supply valve to close off air supply to the tool whenever torque of the tool causes the speed of the motor to decrease below a threshold level. A bypass valve and passage is manually operable to initiate operation of the air motor. An auxiliary low volume, low pressure valve and passage permits an operator to provide minor adjustments of the orientation of the output shaft of the tool. For reverse operation, the speed and acceleration control is eliminated by operation of a reverse operation control mechanism.
