  • Patent number: 10907600
    Abstract: A fuel pump includes a fuel pump housing with a pumping chamber and an outlet valve bore extending along an outlet valve bore axis; a pumping plunger which reciprocates within a plunger bore along a plunger bore axis which is traverse to the outlet valve bore axis; and an outlet valve assembly. The outlet valve assembly includes an outlet valve seat with an outlet flow passage, wherein a first portion of the outlet valve seat is aligned with the pumping plunger in a direction parallel to the plunger bore axis and wherein a second portion of the outlet valve seat is not aligned with the pumping plunger in a direction parallel to the plunger bore axis and an outlet valve member which is moveable between an unseated position which provides fluid communication through the outlet flow passage and a seated position which prevents fluid communication through the outlet flow passage.

  • Patent number: 10900385
    Abstract: A rocker arm includes an outer arm having a first wall surface, a second wall, and a third wall surface together forming a lock member channel. An inner arm selectively pivots relative to the outer arm about a pivot axis. A lost motion spring biases the inner arm to pivot relative to the outer arm in a first direction about the pivot axis. A lock member is located within the lock member channel which moves along a lock member axis between a coupled position which prevents the inner arm from pivoting about the pivot axis and a decoupled position which permits the inner arm to pivot relative to the outer arm. A lock member retainer is spaced apart from, and opposed to, the third wall surface such that the lock member is captured between the lock member retainer and the third wall surface.

  • Patent number: 10871087
    Abstract: A rocker arm includes a body having a first wall and a second with a central opening provided therebetween, the first wall having a first aperture extending therethrough and the second wall having a second aperture extending therethrough. An inner follower within the central opening selectively reciprocates along a reciprocation axis relative to the body, the inner follower extends through the first aperture and the second aperture. A lost motion spring biases the inner follower to move relative to the body along the reciprocation axis in a first direction. A lock member is moveable along a lock member axis between a coupled position which prevents the inner follower from moving past a predetermined position in a second direction which is opposite of the first direction and a decoupled position which permits the inner follower to move past the predetermined position in the second direction.

  • Patent number: 10544711
    Abstract: A rocker arm includes an outer arm having a first wall and a second wall and an inner arm which selectively pivots relative to the outer arm about a pivot shaft axis based on positioning of a lock pin. A lost motion spring includes an outer arm tang grounded to the outer arm and an inner arm tang grounded to the inner arm. A roller shaft is supported by the inner arm and extends toward the first wall. The roller shaft carries a roller which follows a camshaft. A roller retainer is carried by the roller shaft and is located between the roller and the first wall and includes a surface with which the inner arm tang is engaged to ground the lost motion spring to the inner arm through the roller shaft.

  • Patent number: 10519817
    Abstract: A rocker arm includes an outer arm and an inner arm which selectively pivot relative to each other. A lock pin moves between a coupled position in which the lock pin prevents the inner arm from pivoting relative to the outer arm past a predetermined in a first direction and a decoupled position in which the lock pin permits rotation past the predetermined position in the first direction. A lost motion spring biases the inner arm to pivot relative to the outer arm in a second direction which is opposite of the first direction. A travel stop extends along a travel stop axis and has a travel stop surface such that the extent to which the inner arm pivots relative to the outer arm in the second direction is dependent upon the rotational position of the travel stop about the travel stop axis.

  • Patent number: 10465566
    Abstract: A rocker arm includes an outer arm defining a bore; an inner arm which pivots relative to the outer arm, the inner arm defining a stop surface; a lost motion spring which biases the inner arm to pivot relative to the outer arm in a first direction; and a lock pin that slides within the bore between a coupled position in which the lock pin prevents the inner arm from pivoting relative to the outer arm past a predetermined position in a second direction which is opposite of the first direction and a decoupled position in which the lock pin permits the inner arm to pivot relative to the outer arm past the predetermined position in the second direction; such that the lock pin and the stop surface act together to limit the extent to which the inner arm pivots relative to the outer arm in the first direction.

  • Patent number: 10253657
    Abstract: A rocker arm includes an outer arm defining a stop aperture with a stop surface; an inner arm which selectively pivots relative to the outer arm; a latching mechanism which switches the rocker arm between a coupled state in which the inner arm is prevented from pivoting relative to the outer arm in a first direction and a decoupled state in which the inner arm pivots relative to the outer arm; a lost motion spring which biases the inner arm to pivot relative to the outer arm in a second direction which is opposite from the first direction; and a stop pin fixed to the inner arm and extending into the stop aperture such that the stop pin is circumferentially surrounded by the stop surface and such that the stop pin within the stop aperture limits the extent to which the inner arm pivots relative to the outer arm.
