Abstract: A filter has a cup-shaped housing, which includes a liquid inlet, and a lid which includes a liquid outlet. The liquid inlet opens tangentially into a groove around the interior of the mouth of the housing. A baffle covers the groove opening and itself has openings through which the liquid passes. A filter element is mounted centrally within the housing and is surrounded by a sleeve which directs the liquid entering through the baffle towards the closed end of the housing before it passes through the filter to the outlet.

Abstract: The invention relates to internal gear pumps and motors having a pinion meshed with an internal gear and rotatable in a housing, and in which a crescent-shaped member is disposed between the pinion and the internal gear where these are not interengaged. According to the invention a pair of sideplates are arranged to press against opposite axial end faces of the piston and internal gear, one of the plates being fixed and the other movable by hydraulic pressure. The crescent-shaped member is secured relative to the fixed sideplate and is slidable in the other sideplate. A pair of apertures in each sideplate communicate respectively with high- and low-pressure ports in the housing. A sealing element between the crescent-shaped member and the movable sideplate extends over at least that portion of the crescent-shaped member which is adjacent to the aperture connected to the high-pressure port. The sideplates may each be formed with a pair of grooves which extend around opposite sides of the crescent-shaped member from the aperture connected to the low-pressure port. Where such grooves are present the sealing element extends only as far as the ends of grooves, since fluid in these is at low pressure. The sealing element is conveniently carried in a recess in the crescent-shaped member. A sealing element may also be fitted between the crescent-shaped member and the sideplate.

Abstract: A liquid filtering equipment has a body and a lid which respectively include an inlet and an outlet for the fluid to be filtered. A filter element is supported within the body between the inlet and the outlet. The body and lid together may be mounted in a support which also forms part of the equipment and which includes inlet and outlet passages with which the inlet and outlet in the body and lid respectively align. The body and lid may thus be removed as a unit from the support without disturbing the filter element.
